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...

For loop example over an iterable object In the following example, we’re looping over the variableobjand logging each property and value: constobj={"a":"JavaScript",1:"PHP","b":"Python",2:"Java"};for(letkeyinobj){console.log(key+": "+obj[key])}// Output:// "1: PHP"// "...
Or suppose you want to raise the price of everything in your store by 5 cents. Instead of doing these tasks manually, you would want to use a loop. In Java, for loops are used to run a specific task multiple times. Here’s the syntax for a for loop in Java: for (initialization;...
The while loop in Java continually executes a block of statements until a particular condition evaluates to true, else the loop terminates.

The following example demonstrates how you can use forEach() with lambda expression to loop a Map object:// create a map Map<String, Integer> salaries = new HashMap<>(); salaries.put("John", 4000); salaries.put("Alex", 5550); salaries.put("Emma", 3850); salaries.put("Tom", 6000...
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 greater. This isn't the case, so our loop is executed. The loop code prints out the value ofi, which is still ...
