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:

Output:
ShortBuffer 1: [856, 0, 961, 0, 0, 0, 0, 0, 0, 0] ShortBuffer 2: [856, 0, 431, 0, 0] both are not equal
