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]);
}
}
}
}
