When programming in Java, controlling the flow of your code is crucial for efficiency and readability. One common scenario involves the use of loops, particularly the for loop. Sometimes, you may find yourself needing to exit a loop prematurely based on specific conditions. This is where the ...
" means "not" in Java. So the controlling statment is "while not done". The "while loop" can be used forallof your looping needs. However, it is a standard that if you know in advance how many times you need to go through your loop, you use a "for loop". It is considered a ...
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...
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;...

Loop 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()) { System.out.println(...
Java for-loop statement is used to iterate over the arrays or collections using a counter variable that is incremented after each iteration.

.forEach(System.out::println);Copy If we run this, we get the output: cat dogCopy Let’s compare this with the equivalent code in plain Java using aforloop and abreakstatement, to help us see how it works: List<String> list = asList("cat","dog","elephant","fox","rabbit","duc...
For loops will continue to execute a block of code until a condition is met. It is important to note that a for loop will check the condition at the beginning of the loop, not the end. This means that if the condition is met, the loop will not start. For loop syntax is similar ac...
