NumberFormatException resolving help

Question

I got a problem like,
I have a string say "5.22".
The existing code converts to Integer.parseInt("5.22").
The code initially
int j = Integer.parseInt("5.22";
pstmt.setInt(2, j);
Since it is not an Integer NumberFormatException occurs.
The datatype of the value is NUMBER(5). I removed the Integer.parseInt and checked the but something like UNIQUE CONSTRAINT VIOLATION is coming.
My fix
float j = Float.parseFloat("5.22");
pstmt.setFloat(2, j);
error
java.sql.SQLException: ORA-00001: unique constraint
The value is not already present in the table I checked.
Now I need help in,
The datatype of the value in table 'NUMBER(5)' cannot be changed as it is common table for whole project. Is there any way to make the system accept the "5.22" as string then to float and then to Integer?
The value 5.22 should not change while inserting into the table. I tried to convert float to int, Float.parseFloat nothing worked correctly.

The column is effectively defined as an integer. It will only accept integers. There is no way it will accept 5.22. Ever. In the end, you must either round or truncate 5.22.
I tried to convert float to int, Float.parseFloat nothing worked correctly.You can pass it through various functions and transformations until the cows come home. But when the result finally gets to the INSERT, it must be an integer. Period.
