What is the syntax of for loops in java?

Question

Why does this statement give me an error in the program mentioned below? for(int y=0, int z=0; z

The program I used it in is ::

class Testloops
{
     public static void main(String[] args)
     {
         int[] x={ 7,6,5,2,8,9,3};
          for(int y=0, int z=0; z<x.length;z++)
          {
              y= x[z];
              System.out.println(y+ " ");
          }
     }
}

Get rid of the second int declaration.

for (int y = 0, z = 0; z < x.length; z++) {

You are almost there, remove the int type before z=0, then it will work!

for(int y=0, z=0; z < x.length ;z++)

You only need the first int, see a working example here:

You can do this

Declare Y outside the for statement

 int y = 0; 
 int[] x={ 7,6,5,2,8,9,3};

 for (int z=0;z<x.length;z++)
 {
      y= x[z];
      System.out.println(y+ " ");
  }

Not sure why you are declaring y inside the for statement, as its not being iterated?

Reason might be so that the scope of `y` is limited to the `for` loop. – awksp Jul 09 '14 at 16:06
