Java for each loop | enhanced for loop

Java has implemented a new type loop for iterating on all elements called for each loop.

For each loop or enhanced for loop is one of the most simpler loop than others because it has very few statements in the loop.

Note : If you don't know about for loop then please learn for loop statement first to understand this topic.

Syntax

for ( type variableName : arrayVariable )
{
    // body of for each loop
}

For each loop is simple because

• It has very few statements than other loops
• It does not have Initialization , Condition and Increment|Decrement statements.
• It automatically executes all the looping statements.

When for each loop is useful?

• To traverse the array without any condition.
• To print all elements from array from 0th index to last index.
• To visit each and every element incrementing by 1.

Example 1 - Printing all the array elements using for each loop.

public class ForEachTest {

	public static void main(String[] args) 
	{
		int array [] = {2,44,54,64,532};
		
		for (int copyval : array )
		{
			System.out.println("value : "+copyval);	
		}
	}
}

Output

Note : In above example array concept is used. Learn java array to understand this example easily.

Example 2

You can also use other type values but, remember the copyval and arrayvariable type must be matched.

public class Test {

	public static void main(String[] args) 
	{
		String name[]={"Harry","Micky","Jacob","Larry"};
		for (String copyval : name )
		{
			System.out.println("Name : "+copyval);	
		}
	}
}

Output
