The previous example is a common way to create a loop. The intention of the loop is clear, and the exit condition is straightforward:x > 0. In theory, you could make the condition more complex by adding additional variables and comparisons (such asx > 0andy < 0), but this is not con...
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...
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.

This guide will teach us how to break out of theforloop in Java. In programming, certain conditions require breaking the for loop or any other loop for that matter. Let’s take a look. The way to break the current iteration of the loop could not be more simple. You just need to use...

Loop Through a HashMapLoop through the items of a HashMap with a for-each loop.Note: Use the keySet() method if you only want the keys, and use the values() method if you only want the values:ExampleGet your own Java Server // Print keys for (String i : capitalCities.keySet())...
In our earlier articles, we have learned how to loop over ArrayList in Java and you can use the same logic to loop over a TreeSet. You can use both, enhanced for loop and Iterator to traverse over TreeSet in Java. Though worth noting is that Iterator returned by the iterator() method...
and another loop to control how many lines to create. When you are new to nested for loops it can be difficult to determine which loop is the inner loop. In this case, the loop that prints the stars is the inner loop. We need that loop to run each time a new line is created...
