A for loop inside another for loop is called nested for loop. Let’s take an example to understand the concept of nested for loop. In this example, we are printing a pattern using nested for loop. publicclassJavaExample{publicstaticvoidmain(String[]args){//outer loopfor(inti=1;i<=6;i...
Note that all expressions in thefor-loopare optional. In case, we do not provide theterminationexpression, we must terminate the loop inside the statements else it can result in aninfinite loop. 2. Java For-loop Example In the following program, we are iterating over an array ofintvalues....
3. What is the difference between a while loop and a do-while loop in Java? The main difference between a while loop and a do-while loop is that a while loop tests the loop condition before executing the loop body, while a do-while loop executes the loop body at least once and then...
InJava 8, with the introduction ofFunctional InterfaceΛ’s, Java architects have provided us with an Internal Iterator (forEach loop) supported byCollection frameworkand can be used with the collections object. This method performs a given action for each element of the collection. Let’s see ...
To demonstrate a practical example of the for loop, let's create a program that counts to 100 by tens:ExampleGet your own Java Server for (int i = 0; i <= 100; i += 10) { System.out.println(i); } Try it Yourself » In this example, we create a program that only print ...
Let's take a look at how this will work in the Java language. Let's first look at a simple example of 5 laps. This example has a main loop (race track) that will process until the counter reaches 5. However, within each lap around the track, it will step into the nested for ...

A computer program is a set of statements, which are usually executed sequentially. However, in certain situations, it is necessary to repeat certain steps to meet a specified condition. For example, if the user wants to write a program that calculates and displays the sum of the first 10 ...
For example, when looping over an array of numbers you will need to loop over as many times as there are elements in the array. For Loop Structure Java for loops are structured to follow this order of execution: 1) loop initialization 2) boolean condition – if true, continue to next ...
