for and while loops
by Abhir Joshi 17 Jan '02

17 Jan '02

Hi In the source code of some packages, I have seen 'for (;;)' where 'while (1)' could have done the job. Is it related to the efficiency of the code generated ? I have also seen that the a java decompiler generated 'for(;;)' from the bytecode which was compiled with 'while(true)'. Is it that all 'while' loops are converted to 'for' loops internally before compiling? __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
