how to do array in java code example

Example 1: creating array java

int[] intArray = new int[]{ 1,2,3,4,5,6,7,8,9,10 }

Example 2: java array declaration

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

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: 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]);
      }
   }
}

Example 5: Java create array of array

String[][] arrays = new String[][] { array1, array2, array3, array4, array5 };
