Size of boolean datatype

hi all,
Can anyone tell me, how many bytes are taken by a boolean variable.
Pls support ur answer.
Also let me know, Is there any method in java to calculate the size of
a particular datatype, like sizeof() in c/c++.
Thanks in advance.

Refer the following link
http://www.cafeaulait.org/course/week2/02.html
Yes, that website mentions 1 bit but as I said other
sites mention other sizes. Just because you found it
on that website doesn't mean it is true. Only the
good people at sun know the truth.Ok, I will quote the VM specification which you have to adhere to if you implement a VM. As I said previously: The size is not specified in the JLS, but in the VM specification and you will not have a compatible VM if you aren't following it.:
http://java.sun.com/docs/books/vmspec/2nd-edition/html/Overview.doc.html
"3.3.4 The boolean Type
Although the Java virtual machine defines a boolean type, it only provides very limited support for it. There are no Java virtual machine instructions solely dedicated to operations on boolean values. Instead, expressions in the Java programming language that operate on boolean values are compiled to use values of the Java virtual machine int data type.
The Java virtual machine does directly support boolean arrays. Its newarray instruction enables creation of boolean arrays. Arrays of type boolean are accessed and modified using the byte array instructions baload and bastore.2
The Java virtual machine encodes boolean array components using 1 to represent true and 0 to represent false. Where Java programming language boolean values are mapped by compilers to values of Java virtual machine type int, the compilers must use the same encoding. "

  • Does bitwise operation on boolean datatypes work like logical operation ?

    Does bitwise operation on boolean datatypes work like logical operation ?
    For example, in the following code, how is each bitwise operation (say) 'b1 & b2' evaluated ?
    1) by converting the values of b1 (true) and b2 (false) to binary and doing '&' on them OR
    2) just treating it as a logical operation (i.e. similar to &&) where both have to be equal to be true
    Also, does the outcome of the if condition need to result in a 'true' or 'false' for the relevant message to print ? ....... Just fyi, I tried out this program and it goes to condition 2 but I do not understand why.
    class SSBool {
    public static void main(String[] args) {
    boolean b1 = true;
    boolean b2 = false;
    boolean b3 = true;
    if (b1 & b2 | b2 & b3 | b2)
    System.out.println ("condition 1");
    if (b1 & b2 | b2 & b3 | b2 | b1)
    System.out.println ("condition 2");
    Thank you,
    AG

    The Java Tutorial (always my first stop if I need an answer) says :
    "When both operands are boolean, the operator & performs the same operation as &&."
    That your program goes to condition 2 is obvious because the last test in the if-clause if (b1 & b2 | b2 & b3 | b2 | b1) looks at b1 which is true...

  • SIZE of Boolean

    public static void main(String args[])
    System.out.println(Integer.SIZE);
    System.out.println(Float.SIZE);
    System.out.println(Byte.SIZE);
    System.out.println(Short.SIZE);

    This code compile well and run well.
    But when I Write a Statement to find the size of Boolean It is showing error
    System.out.println(Boolean.SIZE);   //Error
    What will the Exact Statement???

    When when any and all data types are used, they are converted into a 32bit integer. Even longs, which is why operations on them arent carried out atomically. When a boolean is being stored in memory and not active, it's stored as a byte. Run a program with either one of the following:
    byte[] bytes = new byte[100000];
    boolean[] booleans = new boolean[100000];The memory usage is the same.

  • What is the size of boolean?

    I read the Java Language Specification. It mentioned the size of int, long, char etc, except boolean. The type boolean is also primitive type in Java, why doesn't Java define its size?

    The JVM doesn't have a notion of booleans. booleans are integral values (zero or not). In Sun's typical 32 bit implementations
    everything except doubles and longs take up four bytes in a class or object. booleans take up one byte in a boolean[]. Note
    that this is only true in nowadays Sun's Java implementations

  • LVFontTypeDef.ctl "Size" has other datatype than size of property size

    Hi,
    the Datatype of the property size of an control (for example caption --> size) has an other datatype than the size in the used LVFontTypeDef.ctl.
    Here we have a difference between u16 --> datatype of size of LVFontTypeDef.ctl and the property size of caption or label or anything else --> u32
    Whats the correct one? Hope its u16.
    regards,
    Daniel
    Attachments:

    Font Size property.png ‏10 KB

    Does it matter?  Whether it is a U16 or a U32, the largest possible number is still way larger than any reasonable font size you'll ever use.
    From where did you get the context help that shows font size as a U32?
    Okay, I see where the other Font.Size came from.  It seems like the Font Size is sized as a U16 when it is a part of the Caption.Font cluster, but becomes a U32 when it is Caption.Font.Size as a property node.
    It seems like a very inconsistent definition of that property and probably should be flagged for investigation by NI.
    This image should give a clearer picture.

  • Size of boolean primitive

    hi,
    in "Thinking in Java", Bruce Eckel writes that the size of the boolean primitive is not explicitly defined in Java (unlike int, long, etc.). He states that it is only specified to be able to take the literal values true and false.
    Is this correct and can anyone provide me with a reference (e.g., to the JLS, or similar)?
    thanks,
    Alan

    The JLS doesn't specify the "size" of anything, as far
    as I can see. But I suppose it depends on what you
    mean by "size"; the JLS does say that a "byte" is an
    8-bit integer, but it doesn't require an
    implementation to store it in any particular way (as
    far as I know). Likewise it says that a "boolean"
    represents a "logical quantity with two possible
    values", i.e. a single bit, but doesn't mandate how an
    implementation should store it.I was about to agree with DrClap (and was looking for the reference to support this); however...
    I looked in the specification for the Virtual Machine and found that the exact storage appears to be specified for every primitive except boolean, float, and double.
    3.3 Primitive Types and Values
    The primitive data types supported by the Java virtual machine are the numeric types, the boolean type (�3.3.4),1 and the returnAddress type (�3.3.3). The numeric types consist of the integral types (�3.3.1) and the floating-point types (�3.3.2). The integral types are:
    - byte, whose values are 8-bit signed two's-complement integers
    - short, whose values are 16-bit signed two's-complement integers
    - int, whose values are 32-bit signed two's-complement integers
    - long, whose values are 64-bit signed two's-complement integers
    - char, whose values are 16-bit unsigned integers representing Unicode characters (�2.1)
    The floating-point types are:
    - float, whose values are elements of the float value set or, where supported, the float-extended-exponent value set
    - double, whose values are elements of the double value set or, where supported, the double-extended-exponent value set
    The values of the boolean type encode the truth values true and false.
    The floating-point types are float and double, which are conceptually associated with the 32-bit single-precision and 64-bit double-precision format
    Apparently the boolean representation is only specified when mapping them to ints:
    The Java virtual machine encodes boolean array components using 1 to represent true and 0 to represent false. Where Java programming language boolean values are mapped by compilers to values of Java virtual machine type int, the compilers must use the same encoding.

  • Boolean Datatype declaration in PowerBuilder...Please HELP

    Hi,
    I have Oracle Stored procedure with last parameter as boolean, When I am calling this stored procedure in
    PowerBuilder 6.5 in the DECLARE I am getting compilation error and it is not working...
    I heard that there is some round about way to solve this problem...
    Any one knows the solution...please help me out...

    I don't know about PowerBuilder but we had a similar problem with Java not understanding Oracle's BOOLEAN implementation. I'm afraid we solved this by substituting a VARCHAR2 parameter with values of 'TRUE' and 'FALSE'. Not very elegant I'm afraid, but if your stored procedure is in a package you can at least overload it.
    cheers, APC

  • Array to cluster with adjustable cluster size

    Hi all
    Here I have  a dynamic 1D array and I need to convert it into cluster. So I use Array to Cluster function. But I notice that the cluster size is a fix value. How can I adjust the cluster size according to the 1D array size?
    Anyone pls give advise..
    Thanks....

    I won't disagree with any of the previous posters, but would point out a conversion technique I just recently tried and found to work well for my own particular purposes.  I've given the method a pretty good workout and not found any obvious flaws yet, but can't 100% guarantee the behavior in all settings.
    Anyhow, I've got a fairly good sized project that includes quite a few similar but distinct clusters of booleans.  Each has been turned into a typedef, complete with logical names for each cluster element.  For some of the data processing I do, I need to iterate over each boolean element in a cluster, do some evaluations, and generate an output boolean cluster.  I first structured the code to use the "Cluster to Array" primitive, then auto-index over the resulting array of booleans, perform the evaluations and auto-index an output array-of-booleans, then finally convert back using the "Array to Cluster" primitive.  I, too, was kinda bothered by having to hardcode cluster sizes in there...
    I found I could instead use the "Typecast" primitive to convert the output array back to my cluster.  I simply fed the input cluster into the middle terminal to defin! the datatype.  Then the output cluster is automatically the right size and right datatype.
    This still is NOT an adjustable cluster size, but it had the following benefits:
    1. If the size of my typedef'ed cluster changes during development by adding or removing boolean elements, none of the code breaks!  I don't have to go searching through my code for all the "Array to Cluster" primitives, identifying the ones I need to inspect, and then manually changing the cluster size on them one at a time!
    2. Some of my processing functions were quite similar to one another.  This method allowed me to largely reuse code.  I merely had to replace the input and output clusters with the appropriate new typedef.  Again, no hardcoded cluster sizes hidden in "Array to Cluster" primitives, and no broken code.
    Dunno if your situation is similar, but it gave me something similar to auto-sizing at programming time.  (You should test the behavior when you feed arrays of the wrong size into the "Typecast" primitive.  It worked for my app's needs, but you should make sure it's right for yours.)

  • Boolean Parameter issue in utl_url.escape

    Hello,
       I am trying to use below query with 2nd parameter as TRUE but I'm getting below error.
    select utl_url.escape(url => 'http://www.sample.com/ümlat.php&\^#q=name', escape_reserved_chars => TRUE) from dual;
    Error:
    [Error] Execution (16: 100): ORA-00904: "TRUE": invalid identifier
    I should pass the parameter as TRUE ( default is FALSE)
    Anyone can support me to over come from this issue.
    FYI - I tried by creating a user defined function and it is working fine but I want to use directly in SELECT statement than using function.

    This isn't an Oracle Text question, but I can probably answer it anyway.
    "TRUE" is a PL/SQL expression for a boolean datatype.  There is no boolean datatype in SQL. Therefore, it is not possible to directly call a PL/SQL procedure requiring a boolean parameter from a SQL select query.  You must wrap it in a procedure using only SQL datatypes, as you have suggested.

  • Boolean operators in the WHERE clause

    I'd like to create an operator which would allow me to use the following syntax in the where clause:
    select 1 from dual where iplike('172.16.0.128', '*.*.*.*');
    I've created a function (iplike_bool_fn) to implement my desired check, and attempted to bind an operator to it:
    create or replace operator iplike binding(varchar,varchar) return boolean using iplike_bool_fn;
    The binding fails with: ORA-06553: PLS-201: identifier 'OPENNMS.BOOLEAN' must be declared
    I acknowledge the 'no boolean in SQL' issue, however, I don't understand how several built-in operators appear to work fine this way:
    select 1 from dual where REGEXP_LIKE('test','test');
    Is there a way to construct a user defined operator that will allow this syntax?

    SQL does not recognise the Boolean datatype returning TRUE/FALSE as a valid datatype. Your function would have to return a value of, say, 0 or 1 and then you compare the result of the function to those values to determine your match or not.
    Alternatively, depending on your database version, you could use regular expressions (REGEXP_LIKE) to do your comparison, which would remove the need to call any PL/SQL code (which degrades the performance of SQL).
    PS. So in short, the answer to your question is No, you can't construct your own type of function like this.

  • No BOOLEAN in Oracle 8i ???

    I'm migrating a schema from Postgres to Oracle 8i, and Oracle chokes on boolean data types. I'm looking at different data types lists for Oracle, and Boolean is never present. So, ... could it be that it doesn't have one???
    How can I translate this:
    CREATE TABLE (
    myBoolean BOOLEAN
    ... for Oracle 8i?
    Any help greatly appreciated.
    Miguel

    Oracle 8i SQL language does not have a BOOLEAN datatype so you can't store BOOLEAN values in a database. I use a CHAR(1) datatype because it only occupies one byte but the downside is that conversion and testing can be a bit messy. You could use a LONG which would be easier to manipulate but then each "BOOLEAN" will take up 4 bytes.
    Curiously Oracle PL/SQL has a BOOLEAN datatype but the manual reminds the user that you can't store it as such in a database :)

    http://docs.oracle.com/cd/B28359_01/server.111/b28310/tables006.htm#i1006645
    Use the ALTER TABLE...MODIFY statement to modify an existing column definition. You can modify column datatype, default value, column constraint, column expression (for virtual columns) and column encryption.
    You can increase the length of an existing column, or decrease it, if all existing data satisfies the new length. You can change a column from byte semantics to CHAR semantics or vice versa. You must set the initialization parameter BLANK_TRIMMING=TRUE to decrease the length of a non-empty CHAR column.
    If you are modifying a table to increase the length of a column of datatype CHAR, realize that this can be a time consuming operation and can require substantial additional storage, especially if the table contains many rows. This is because the CHAR value in each row must be blank-padded to satisfy the new column length.
    And the ALTER TABLE statement in the SQL Language doc
    http://docs.oracle.com/cd/B28359_01/server.111/b28286/statements_3001.htm#SQLRF01001
    modify_col_properties
    Use this clause to modify the properties of the column. Any of the optional parts of the column definition (datatype, default value, or constraint) that you omit from this clause remain unchanged.
    datatype You can change the datatype of any column if all rows of the column contain nulls. However, if you change the datatype of a column in a materialized view container table, then Oracle Database invalidates the corresponding materialized view.
    You can omit the datatype only if the statement also designates the column as part of the foreign key of a referential integrity constraint. The database automatically assigns the column the same datatype as the corresponding column of the referenced key of the referential integrity constraint.
    You can always increase the size of a character or raw column or the precision of a numeric column, whether or not all the rows contain nulls. You can reduce the size of a datatype of a column as long as the change does not require data to be modified.The database scans existing data and returns an error if data exists that exceeds the new length limit.

Maybe you are looking for
