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
