What does these codees mean?

Question

Pls help me with the meaning of the following codes,
1. int count;
for (int i = 0; i<COUNT.length; i++)
count = Integer.parseInt(COUNT);
2. if(POINT.compareTo("R") != 0)
3.if (COUNT_02.compareTo("0") != 0)
4.result.addValue(EAN_04count_EAN+3);
5.result.addValue(EAN_04count_EAN+3);
6.result.addValue(Quantitycount_qty);
Also can u suggest some urls where some documaents can be available to enhance Java skills to develop UDFs.
Points will be awarded. Pls help. I hav been assigned huge responsibilities in XI, though I am an Abaper!
PS: Can u suggest any PDF where I can come to know about the different syntax, commands as used above, so that I can develop my own java codes....

Answer 1

Hi,
1. int count;
   for (int i = 0; i<count.length; i++)
       count = Integer.parseInt(count);
Ans: Here Count is a variable and all the count variables should be changed to an Object.
2. if(POINT.compareTo("R") != 0)
Ans: Here POINT should be a String Constant
public int compareTo(String anotherString)
Compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by this String object is compared lexicographically to the character sequence represented by the argument string. The result is a negative integer if this String object lexicographically precedes the argument string. The result is a positive integer if this String object lexicographically follows the argument string. The result is zero if the strings are equal; compareTo returns 0 exactly when the equals(Object) method would return true.
3. if (COUNT_02.compareTo("0") != 0)
Ans : Same as (2)
4. result.addValue(EAN_04count_EAN+3);
Ans: Here what is result ?  Check for result.addValue method in Java API @ http://java.sun.com/j2se/1.5.0/docs/api/
5.result.addValue(EAN_04count_EAN+3);
Ans: Same as 4
6.result.addValue(Quantitycount_qty);
Ans: Same as 4
