11 gru 2018 · There may be many ways of iterating over an array in Java, below are some simple ways. Method 1: Using for loop: This is the simplest of all where we just have to use a for loop where a counter variable accesses each element one by one. // Java program to iterate over an array. // using for loop.
public class PQarray1 {. } public static void main(String[] args) { int[] a = new int[6]; int[] b = new int[a.length]; b = a; for (int i = 1; i < b.length; i++) b[i] = i; for (int i = 0; i < a.length; i++) System.out.print(a[i] + " "); System.out.println();
Java for loop is used to run a block of code for a certain number of times. The syntax of for loop is: for (initialExpression; testExpression; updateExpression) { // body of the loop }
