ShortBuffer equals() method in Java with Examples

The equals() method of java.nio.ShortBuffer Class is used to check whether or not the given buffer is equal to another object.

Two short buffers are equal if, and only if,

• They have the same element type,
• They have the same number of remaining elements, and
• The two sequences of remaining elements, considered independently of their starting positions, are pointwise
  equal.

A short buffer is not equal to any other type of object.

Syntax:

public boolean equals(Object ob)

Parameters: This method takes the ob, the object to which this buffer is to be compared, as a parameter.

Return Value: This method returns true if, and only if, this buffer is equal to the given object.

Below are the examples to illustrate the equals() method:

Program 1:

// Java program to demonstrate
// equals() method

import java.nio.*;
import java.util.*;

public class GFG {

    public static void main(String[] args)
    {

        // Declaring the capacity of the ShortBuffer 1
        int capacity1 = 10;

        // Declaring the capacity of the ShortBuffer 2
        int capacity2 = 10;

        // Creating the ShortBuffer
        try {

            // creating object of Shortbuffer 1
            // and allocating size capacity
            ShortBuffer sb1 = ShortBuffer.allocate(capacity1);

            // creating object of Shortbuffer 2
            // and allocating size capacity
            ShortBuffer fb2 = ShortBuffer.allocate(capacity2);

            // putting the value in Shortbuffer 1
            sb1.put((short)856);
            sb1.put(2, (short)961);
            sb1.rewind();

            // putting the value in Shortbuffer 2
            fb2.put((short)856);
            fb2.put(2, (short)961);
            fb2.rewind();

            // print the ShortBuffer 1
            System.out.println(" ShortBuffer 1: "
                               + Arrays.toString(sb1.array()));

            // print the ShortBuffer 2
            System.out.println(" ShortBuffer 2: "
                               + Arrays.toString(fb2.array()));

            // checking the equality of both ShortBuffer
            boolean fbb = sb1.equals(fb2);

            // checking if else condition
            if (fbb)
                System.out.println("both are equal");
            else
                System.out.println("both are not equal");
        }

        catch (IllegalArgumentException e) {
            System.out.println("IllegalArgumentException catched");
        }

        catch (ReadOnlyBufferException e) {
            System.out.println("ReadOnlyBufferException catched");
        }
    }
}

Output:

ShortBuffer 1: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0]
ShortBuffer 2: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0]

both are equal

Program 2:

// Java program to demonstrate
// equals() method

import java.nio.*;
import java.util.*;

public class GFG {

    public static void main(String[] args)
    {

        // Declaring the capacity of the ShortBuffer 1
        int capacity1 = 10;

        // Declaring the capacity of the ShortBuffer 2
        int capacity2 = 5;

        // Creating the ShortBuffer
        try {

            // creating object of Shortbuffer 1
            // and allocating size capacity
            ShortBuffer sb1 = ShortBuffer.allocate(capacity1);

            // creating object of Shortbuffer 2
            // and allocating size capacity
            ShortBuffer sb2 = ShortBuffer.allocate(capacity2);

            // putting the value in Shortbuffer 1
            sb1.put((short)856);
            sb1.put(2, (short)961);
            sb1.rewind();

            // putting the value in Shortbuffer 2
            sb2.put((short)856);
            sb2.put(2, (short)431);
            sb2.rewind();

            // print the ShortBuffer 1
            System.out.println(" ShortBuffer 1: "
                               + Arrays.toString(sb1.array()));

            // print the ShortBuffer 2
            System.out.println(" ShortBuffer 2: "
                               + Arrays.toString(sb2.array()));

            // checking the equality of both ShortBuffer
            boolean fbb = sb1.equals(sb2);

            // checking if else condition
            if (fbb)
                System.out.println("both are equal");
            else
                System.out.println("both are not equal");
        }

        catch (IllegalArgumentException e) {
            System.out.println("IllegalArgumentException catched");
        }

        catch (ReadOnlyBufferException e) {
            System.out.println("ReadOnlyBufferException catched");
        }
    }
}

Output:

ShortBuffer 1: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0]
ShortBuffer 2: [856, 0, 431, 0, 0]

both are not equal
