loop inside an array code example

Example 1: how to loop through an array

int[] numbers = {1,2,3,4,5};
for (int i = 0; i < numbers.length; i++) {
	System.out.println(i);
}

Example 2: iterate through an array

var arr = [1,2,3,4,5,6,7,8];

// Uses the usual "for" loop to iterate
for(var i= 0, l = arr.length; i< l; i++){
	console.log(arr[i]);
}

console.log("========================");

//Uses forEach to iterate
arr.forEach(function(item,index){
	console.log(item);
});
