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 to be executed }...
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(...
negative, and zero numbers in the array are shown in this example. A numeric array of 10 elements is defined in the code. Thelengthproperty is used in Java to count the total number of elements of an array object. It is used in the‘for’loop to define the number of ...
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...

"For ... Next". "While ... Wend". "Do While ... Loop". "Do Until ... Loop". "Do ... Loop While". "Do ... Loop Until". "For Each ... Next" - Used with arrays and collections. See the array chapter for details.
For each.This is a simple syntax form. If we loop over a collection, we use a colon, not an index variable. This enumerates each element in the collection (array, ArrayList).Array Info:This is called a foreach-loop statement. The Java language does not support a "foreach" keyword. ...
Meaning, the loop terminates if the statement expression/ condition becomes false. This structure allows programmers to control the flow of their code and perform repetitive tasks with ease. Syntax Of For Loop In C++ for (initialization; condition; increment/decrement) {// code to be executed} ...
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. ...
InputStream is = LoopElimination.class.getResourceAsStream("/testfile.txt"); // while loop with clumsy looking syntax int c; while((c = is.read()) != -1) { System.out.print((char)c); } // But this is even uglier InputStream nis = LoopElimination.class.getResourceAsStream(...
