ShortBuffer equals() method in Java with Examples
Last Updated :
20 Sep, 2018
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
// 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
// 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
