How to get Sub Array in Java ?

Answer

To get a subarray from a given array in Java, you can use the Arrays.copyOfRange() method.

✐ Examples

1 Get Subarray from Integer Array

In this example,

We create an integer array named numbers with some elements.
We get a subarray of the array from index 1 to 3 using the Arrays.copyOfRange() method and store the result in the variable subArray.
Finally, we print the subarray to the console.

Java Program

import java.util.Arrays;
public class Main {
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5};
        int[] subArray = Arrays.copyOfRange(numbers, 1, 4);
        System.out.println("Subarray: " + Arrays.toString(subArray));
    }
}

Output

Subarray: [2, 3, 4]

2 Get Subarray from String Array

In this example,

We create a string array named words with some elements.
We get a subarray of the array from index 1 to 3 using the Arrays.copyOfRange() method and store the result in the variable subArray.
Finally, we print the subarray to the console.

Java Program

import java.util.Arrays;
public class Main {
    public static void main(String[] args) {
        String[] words = {"apple", "banana", "cherry", "date", "elderberry"};
        String[] subArray = Arrays.copyOfRange(words, 1, 4);
        System.out.println("Subarray: " + Arrays.toString(subArray));
    }
}

Output

Subarray: [banana, cherry, date]
