arrays method in java code example

Example 1: 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 2: arrays 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]);
      }
   }
}

Example 3: array in java

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

Example 4: 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 array
