for (int i=0; i<intArray.length; i++) { System.out.println(intArray[i]); } 3) A complete Java int array example Sometimes it helps to see source code used in a complete Java program, so the Java class/program below demonstrates the different Java int array examples. The method nam...
A commonexample of the Java array length propertybeing used in code is a program looping through all of the elements in an array. The following Java array length example prints out every number in an array named fibArray: int[] fibArray = {0,1,1,2,3,5,8};for(inti=0; i < fibArr...
