When you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop:SyntaxGet your own Java Server for (statement 1; statement 2; statement 3) { // code block
Note:In the above example, I have declared the num as int in the enhanced for loop. This will change depending on the data type of array. For example, theenhanced for loop for string typewould look like this: Stringarr[]={"hi","hello","bye"};for(Stringstr:arr){System.out.println(...
publicclassArrayIterationExample{publicstaticvoidmain(String[]args){int[]numbers={10,20,30,40,50};for(int i=0;i<numbers.length;i++){System.out.println("Element at index "+i+": "+numbers[i]);}}} This example demonstrates iterating over an array. The loop iterates through thenumbersar...

Expression 1 sets a variable before the loop starts (let i = 0). Expression 2 defines the condition for the loop to run (i must be less than 5). Expression 3 increases a value (i++) each time the code block in the loop has been executed. ...
For Each Loop Java When you’re working with an array and collection, there is another type of for loop you can use to iterate through the contents of the array or collection with which you are working. This is called a for-each loop, or an enhanced for loop. The syntax for the for...
Nested Loop The cool thing about Python loops is that they can be nested i.e. we can use one or more loops inside another loop. This enables us to solve even more complex problems. #1) Nesting for Loops for loops can be nested within themselves. The syntax below shows a 1-level neste...
Another common control flow is a loop. Go uses only one looping construct, and that's aforloop. But you can represent loops in more than one way. In this part, you'll learn about the loop patterns that Go supports. Basic for loop syntax ...
Other programming languages also implement for loops, but their syntax and capabilities can vary. Languages like C and Java use a more traditional approach, where the loop is controlled by initializing a variable, setting a loop continuation condition, and defining the iteration step. This structure...
