Declare string array in Java (one and two dimensional)

                         

In this section we will learn how to declare string array in java. Java provides many ways to declare an array and initialize them for example- with 'new' keyword, without new keyword. Here we have given example to declare, initialize and access elements of one dimensional array and two dimensional as well.

1. String arr[] = new String[] {"mahendra", "anu", "girish", "komal"};
2. String arr[] = {"mahendra", "anu", "girish", "komal"};


 

 

 

ArrayDimensions.java

public class ArrayDimensions {
    public static void main(String[] args) {
        //declare and initialize one dimension array
        String[] names = new String[]{"mahendra", "anu", "girish", "komal"};
        System.out.println("These are elements of one Dim array.");
        for (int i = 0; i < names.length; i++) {
            System.err.println(names[i] + "   ");
        }
        //declare and initialize two dimensional array
        String dim2[][] = {
            {"mahendra", "girish"},
            {"sandeep", "vinnet"},
            {"amit", "komal"}
        };
        System.out.println("These are elements of two Dim array.");
        for (int i = 0; i < 3; i++) {
            for (int j = 0; j < 2; j++) {
                System.out.println(dim2[i][j]);
            }
        }
    }
}

Output :

These are elements of one Dim array.
mahendra   
anu   
girish   
komal   
These are elements of two Dim array.
mahendra
girish
sandeep
vinnet
amit
