Java's foreach statement

foreach is a special, simplified version of a for statement, but any time a foreach statement can be rewritten as a for statement. The foreach statement provides a great convenience for programmers in terms of traversing arrays, etc.

The syntax is as follows:

for (element variable x: Traverse object obj) {

Java statements that reference X

}

Instance:

Package Foreach1;

Public class Foreach1 {

Public static void main (string[] args) {

int [] arr={1,3,5,7,9,11,13,15}; //Declare one-dimensional array

System. out. println ("The number in a one-dimensional array is:");

For the variable referenced by the for (int x:arr) { //int x,arr formulates an array to iterate through, Last output x value

System. out. Print (x+"");

        }

    }

}
