Question

Syntax of for each loop n it's application

Answer 1

Here's an example to iterate through elements of an array using standard for loop:

class ForLoop {

public static void main(String[] args) {

char[] vowels = {'a', 'e', 'i', 'o', 'u'};

for (int i = 0; i < vowels.length; ++ i) {

System.out.println(vowels[i]);

}

}

}

You can perform the same task using for-each loop as follows:

class AssignmentOperator {

public static void main(String[] args) {

char[] vowels = {'a', 'e', 'i', 'o', 'u'};

// foreach loop

for (char item: vowels) {

System.out.println(item);

}

}

}

The output of both programs will be same:

a

e

i

o

u
