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 komal |
