array 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]);array in java
Size is fixed
It supports both primitives and objects
Can be also multi-dimensionalarrays in java
For example: int[ ] num = new int[6];
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]);
}
}
}array in java
int intArray[]; //declaring array
intArray = new int[10]; // allocating memory to array
intArray[0] = 10; // Adding elements to the array
System.out.println(intArray[0]); // Accessing elements of arrayarray in java
// datatype var = new datatype[size]
int[] arr = new int[10];
// OR
int arr[] = new int[10];Copyright © 2021 Codeinu
