In thisJava Tutorial, we explored various types of loops in Java. We covered the syntax and usage of thefor,while,do-while, and enhancedfor-eachloops, along with an example of nested loops. Understanding these looping constructs is fundamental for performing repetitive tasks and iterating through...
// This is the Hello program in Java class Hello { public static void main (String args[]) { int i; /* Now let's say hello */ System.out.print("Hello "); for (i=0; i < args.length; i = i++) { System.out.print(args[i]); System.out.print(" "); } System.out.printl...

Many tasks within a program are repetitive, such as prompting for data, counting values, and so on. The for loop allows the execution of a block of code for a given control function. The following is an example format; if there is only one statement in the block then the braces can ...

Its capabilities may be expanded by libraries written in Python, Java, or various other programming languages. It is surrounded by a large ecosystem of libraries and tools built as different projects. The Selenium library is the most widely used library for web development and UI testing. In ...

The second basic type of loop in Java that I will discuss is the "while loop". A while loop is actually just a conditional that repeats itself as long as the condition stays true. It looks a lot like an if statement. Here take a look: ...

In the above code, i is initialized to 1 before the start of the loop. The test condition, i<=10 is evaluated. If true, the body of the loop executes. If the condition becomes false in the beginning itself, the program control does not even enter the loop once. The loop executes un...
