array example java

Example 1: java array declaration

int[] array = new int[/*size*/];
// Works for double, char, etc.

Example 2: java int array

int[] theNumbers = new int[5];

arr[0] = 4;
arr[1] = 8;
arr[2] = 15;
arr[3] = 16;
arr[4] = 23;
arr[5] = 42;

Example 3: 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]);

Example 4: how to use arrays java

// How to use arrays 
// Julian
 public static void main(String[] args)
   {
   // Initialize array
      int[] arrNum = {25, 23, 15, 20, 24};
   // Recorrerlo
      for(int a = 0; a < arrNum.length; a++)
      {
         System.out.println(arrNum[a]);
      }
   }

Example 5: array in java

Size is fixed
It supports both primitives and objects
Can be also multi-dimensional
