how to declare array java
int intArray[]; //declaring array
intArray = new int[20]; // allocating memory to array
//OR
int[] intArray = new int[20]; // combining both statements in onehow to declare array java
int intArray[]; //declaring array
intArray = new int[20]; // allocating memory to array
//OR
int[] intArray = new int[20]; // combining both statements in onearray in java
//method 1
int[] age = new int[3];
age[0] = 1;
age[1] = 3;
age[2] = 6;
for (int i=0; i < 3; i++)
System.out.println(age[i]);
//method 2
int[] num = {3,3,5};
//int num[] = {3,3,5}; also works the same
System.out.println(num[0]);Arrays in java
// Accessing array elements using for loop
public class AccessingArrayElements
{
public static void main(String[] args)
{
int[] arrNum = {25, 23, 15, 20, 24};
for(int a = 0; a < arrNum.length; a++)
{
System.out.println(arrNum[a]);
}
}
}make an array java
//you can do it like this
int[] arr = {10, 20, 30, 40};
//or this
int arr = new int[4];Java create array of array
String[][] arrays = new String[][] { array1, array2, array3, array4, array5 };Copyright © 2021 Codeinu
