length function for string

[Rajesh Veluchamy]

hi,
For static data, the below code is fine,

char data[] = {'a', 'b', 'c'};
for(int i=0;i<3;i++)
   System.out.println(data[i]);    

but in runtime if the length of data is reduced, it throws exception
i have read something like length function

may be "data.length"

Thanks to all, in advance

String have a length method. And arrays have a length property. See the JavaDocs for more.

I think you should have given a bit more detail, Paul.

You could write "for(int i = 0; i < data.length; i++). . ." or "for(int i = 0; i < myString.length(); i++). . ."

but for an array, if you simply want to go through all the elements, use the "enhanced for" loop, (sometimes called the for-each loop), but you can't say "c = anything".

for(char c : data)
{
   System.out.println(c);
}//end for-each loop
