array [i][j] code example

Example: arrays

// Java program to demonstrate working of Arrays.toString() 
import java.io.*; 
import java.util.*; 

class GFG { 
	public static void main(String[] args) 
	{ 
		// Let us create different types of arrays and 
		// print their contents using Arrays.toString() 
		boolean[] boolArr = new boolean[] { true, true, false, true }; 
		byte[] byteArr = new byte[] { 10, 20, 30 }; 
		char[] charArr = new char[] { 'g', 'e', 'e', 'k', 's' }; 
		double[] dblArr = new double[] { 1, 2, 3, 4 }; 
		float[] floatArr = new float[] { 1, 2, 3, 4 }; 
		int[] intArr = new int[] { 1, 2, 3, 4 }; 
		long[] lomgArr = new long[] { 1, 2, 3, 4 }; 
		Object[] objArr = new Object[] { 1, 2, 3, 4 }; 
		short[] shortArr = new short[] { 1, 2, 3, 4 }; 

		System.out.println(Arrays.toString(boolArr)); 
		System.out.println(Arrays.toString(byteArr)); 
		System.out.println(Arrays.toString(charArr)); 
		System.out.println(Arrays.toString(dblArr)); 
		System.out.println(Arrays.toString(floatArr)); 
		System.out.println(Arrays.toString(intArr));
