Java for-each Loop

Java for-each Loop:

The for-each loop is used to traverse the array or collection in java. It is easier to use than simple for loop because we don’t need to increment value and use subscript notation. It works on the basis of an element, not an index. It returns elements one by one in the defined variable.

Syntax of Java for-each Loop:

Example 1: Printing Array using for-each loop.

public class For_each_loop {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		String [] subjects = {"computer","maths","chemistry","physics"};
		
		for(String x : subjects) {
			
			System.out.println(x);
		}
	}

}

Example 2: Printing ArrayList using for-each loop

import java.util.ArrayList;

public class For_each_loop {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		
		ArrayList<String> subjects = new ArrayList<String>();
		
		subjects.add("computer");
		subjects.add("maths");
		subjects.add("chemistry");
		subjects.add("physics");
		
		for(String x : subjects) {
			
			System.out.println(x);
		}
	}
