put(int i)
The put(int i) method of java.nio.IntBuffer Class is used to write the given int into the newly created int buffer at the current position, and then increments the position.
Syntax :
public abstract IntBuffer put(int i)
Parameters: This method takes the int value i as a parameter which is to be written in int buffer.
Return Value: This method returns this buffer, in which the int value is inserted.
Exception: This method throws the following exceptions:
- BufferOverflowException- If this buffer’s current position is not smaller than its limit
- ReadOnlyBufferException- If this buffer is read-only
Below are the examples to illustrate the put(int i) method:
Example 1:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 3;
try {
IntBuffer ib = IntBuffer.allocate(capacity);
ib.put(8);
ib.put(9);
ib.put(7);
ib.rewind();
System.out.println("Original IntBuffer: "
+ Arrays.toString(ib.array()));
}
catch (BufferOverflowException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}
|
Output:
Original IntBuffer: [8, 9, 7]
Example 2: To demonstrate BufferOverflowException.
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 3;
try {
IntBuffer ib = IntBuffer.allocate(capacity);
ib.put(8);
ib.put(9);
ib.put(7);
System.out.println("Trying to put the Int at the "
+ "position more than its limit");
ib.put(7);
ib.rewind();
System.out.println("Original IntBuffer: "
+ Arrays.toString(ib.array()));
}
catch (BufferOverflowException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}
|
Output:
Trying to put the Int at the position more than its limit
Exception throws : java.nio.BufferOverflowException
Examples 3: To demonstrate ReadOnlyBufferException.
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 3;
try {
IntBuffer ib = IntBuffer.allocate(capacity);
IntBuffer ib1 = ib.asReadOnlyBuffer();
System.out.println("Trying to put the Int value"
+ " in read only buffer");
ib1.put(8);
}
catch (BufferOverflowException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}

Output:
Trying to put the Int value in read only buffer
Exception throws : java.nio.ReadOnlyBufferException
put(int index, int i)
The put(int index, int i) method of java.nio.IntBuffer Class is used to write the given int into the buffer at the given index.
Syntax:
public abstract IntBuffer put(int index, int i)
Parameters: This method takes the following arguments as a parameter:
- index: The index at which the int will be written
- i: The int value to be written
Return Value: This method returns this buffer.
Exception: This method throws the following exception:
- IndexOutOfBoundsException- If index is negative or not smaller than the buffer’s limit
- ReadOnlyBufferException- If this buffer is read-only
Below are the examples to illustrate the put(int index, int i) method:
Example 1:
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 3;
try {
IntBuffer ib = IntBuffer.allocate(capacity);
ib.put(0, 8);
ib.put(2, 9);
ib.put(1, 7);
ib.rewind();
System.out.println("Original IntBuffer: "
+ Arrays.toString(ib.array()));
}
catch (IndexOutOfBoundsException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}
|
Output:
Original IntBuffer: [8, 7, 9]
Example 2: To demonstrate IndexOutOfBoundsException.
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 3;
try {
IntBuffer ib = IntBuffer.allocate(capacity);
ib.put(0, 8);
ib.put(2, 9);
System.out.println("Trying to put the value"
+ " at the negative index");
ib.put(-1, 7);
}
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
Example 3: To demonstrate ReadOnlyBufferException.
import java.nio.*;
import java.util.*;
public class GFG {
public static void main(String[] args)
{
int capacity = 3;
try {
IntBuffer ib = IntBuffer.allocate(capacity);
IntBuffer ib1 = ib.asReadOnlyBuffer();
System.out.println("Trying to put the Int value"
+ " in read only buffer");
ib1.put(0, 8);
}
catch (BufferOverflowException e) {
System.out.println("Exception throws : " + e);
}
catch (ReadOnlyBufferException e) {
System.out.println("Exception throws : " + e);
}
}
}

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