Question

Provide an example of using a for loop without an array.

Answer 1

Answer)

It is with the help of the for-each loop one can use the loop without the array:

The syntax is as follows:

for (String tempStr : dataOfArray) {

System.out.println(tempStr);

}

For example as below:

class ConventionalApproach{

public static void main(String[] args) {

String [ ] dataOfArray = {"One" , "Two" , "Three", "Four"};

System.out.println("Use of the conventional approach for loop and array");

for (int a = 0; a < dataOfArray.length; a ++){

System.out.println(dataOfArray[a]);

}

//With the use of for each loop//
System.out.println("With the help of foreach loop");
for (String tempStr : dataOfArray){
System.out.println(tempStr);
}

}

}
