In this section, you will create your first programming loop in Java using thewhilekeyword. You’ll use a singleintvariable to control the loop. Theintvariable will be calledxand will have an initial value of3. While, or as long as,xis bigger than0, the loop will continue executing a ...
Thefor-loopstatement in Java provides a compact way to iterate over the arrays or collection types using a counter variable that is incremented or decremented after each iteration. Programmers often refer to it as thetraditional “for loop”because of the way it repeatedly loops until a particular...
Here’s a basic structure of a for loop in Java: for (initialization; condition; iteration) { // code to be executed } When the condition evaluates to true, the loop continues to execute. However, there may be situations where you want to exit the loop early. This is where the break...
So we can use return to exit the while-loop too. Check the code below to see how we used return. import java.util.Arrays; import java.util.List; public class SimpleTesting { public static void main(String[] args) { boolean result = show(); if (result) { System.out.println("Loop ...
The while loop in Java continually executes a block of statements until a particular condition evaluates to true, else the loop terminates.

To convert an array to a string using StringBuilder, we have to use a loop to iterate over all array's elements and then call the append() method to append them into the sequence: String[] fruits = {"Apple", "Orange", "Mango", "Banana"}; StringBuilder builder = new StringBuilder()...

To iterate over elements of String Array in Java, use any of the loop statements like while, for or advanced for loop. In this tutorial, we will learn how to iterate over string array elements using different looping techniques in Java with examples.
publicstaticvoidmain(String[] args){ for(inti =1; i <4; i++){ System.out.print(i); } } } //Output: 123 In the example above, the for loop prints out the value ofi. The keywordforinitializes the loop. The variableiis initially set to 1. The condition checks whetheriis four or...
