Java – use methods on each item in the array

I have a dynamically populated string array I want to run this function:

String[] name = request.getParameterValues("name");
myString = name.substring(0,name.length() - 2);

Now, I know this won't work because the substring and length methods are not used for the entire array Since I don't know how many items there are in this array at any given runtime, should I run the substring / length function for each item in this array anyway?

Solution

Yes, you can use the length field of the name array

for (int i = 0; i < name.length; ++i)
{
    String s = name[i];
    String sbtr = s.substring(0,s.length() - 2);
}

Or better:

for (String s: name)
{
    String sbtr = s.substring(0,s.length() - 2);
}
