ShortBuffer put(int, short) method in Java With Examples

The put() method of java.nio.ShortBuffer Class is used to write the given short into this buffer at the given index. 

Syntax:

public abstract ShortBuffer put(int index, short s)

Parameters:

• index:This parameter specifies to the index at which the short will be written.It is optional.
• s:This parameter specifies to the short value to be written

Return Value:This method returns this buffer. 

Exception:

• IndexOutOfBoundsException – If index is negative or not smaller than the buffer’s limit.
• ReadOnlyBufferException – If this buffer is read-only

Below program illustrates the put() method: 

Program 1: 

Java

// Java program to demonstrate put() method

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

public class GFG {

    public static void main(String[] args)
    {

        // Declaring the capacity of the ShortBuffer
        int capacity = 3;

        // Creating the ShortBuffer
        try {

            // creating object of shortbuffer
            // and allocating size capacity
            ShortBuffer sb
                = ShortBuffer.allocate(capacity);

            // putting the value in shortbuffer
            // using put() at index 0
            sb.put(0, (short)400);

            // putting the value in shortbuffer
            // using put() at index 2
            sb.put(2, (short)1000);

            // putting the value in shortbuffer
            // using put() at index 1
            sb.put(1, (short)30);

            // rewinding the shortbuffer
            sb.rewind();

            // print the ShortBuffer
            System.out.println("Original ShortBuffer: "
                               + Arrays.toString(sb.array()));
        }

        catch (IndexOutOfBoundsException e) {

            System.out.println("Exception throws: " + e);
        }

        catch (ReadOnlyBufferException e) {

            System.out.println("Exception throws: " + e);
        }
    }
}

Output:

Original ShortBuffer: [400, 30, 1000]

Program 2: To demonstrate IndexOutOfBoundsException. 

Java

// Java program to demonstrate put() method

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

public class GFG {

    public static void main(String[] args)
    {

        // Declaring the capacity of the ShortBuffer
        int capacity = 3;

        // Creating the ShortBuffer
        try {

            // creating object of shortbuffer
            // and allocating size capacity
            ShortBuffer sb
                = ShortBuffer.allocate(capacity);

            // putting the value in shortbuffer
            // using put() at index 0
            sb.put(0, (short)31);

            // putting the value in shortbuffer
            // using put() at index 2
            sb.put(2, (short)49);

            // putting the value in shortbuffer
            // using put() at index -1
            System.out.println("Trying to put the value"
                               + " at the negative index");
            sb.put(-1, (short)27);
        }

        catch (IndexOutOfBoundsException e) {

            System.out.println("Exception throws: " + e);
        }

        catch (ReadOnlyBufferException e) {

            System.out.println("Exception throws: " + e);
        }
    }
}

Output:

Trying to put the value at the negative index
Exception throws: java.lang.IndexOutOfBoundsException

Program 3: To demonstrate ReadOnlyBufferException. 

Java

// Java program to demonstrate put() method

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

public class GFG {
    public static void main(String[] args)
    {

        // Declaring the capacity of the ShortBuffer
        int capacity = 3;

        // Creating the ShortBuffer
        try {

            // creating object of shortbuffer
            // and allocating size capacity
            // using allocate() method
            ShortBuffer sb
                = ShortBuffer.allocate(capacity);

            // Creating a read-only copy of ShortBuffer
            // using asReadOnlyBuffer() method
            ShortBuffer sb1 = sb.asReadOnlyBuffer();

            System.out.println("Trying to put the float value"
                               + " in read only buffer");

            // putting the value in readonly shortbuffer
            // using put() method
            sb1.put(0, (short)13);
        }

        catch (BufferOverflowException e) {

            System.out.println("Exception throws: " + e);
        }

        catch (ReadOnlyBufferException e) {

            System.out.println("Exception throws: " + e);
        }
    }
}

Output:

Trying to put the float value in read only buffer
Exception throws: java.nio.ReadOnlyBufferException
