get()
The
get() method of
java.nio.ByteBuffer class is used to read the byte at the buffer's current position, and then increments the position.
Syntax :
public abstract byte get()
Return Value: This method returns the byte at the buffer's current position.
Throws: This method throws
BufferUnderflowException – If the buffer’s current position is not smaller than its limit, then this exception is thrown.
Below are the examples to illustrate the
get() method:
Examples 1:
Output:
Original ByteBuffer: [20, 30, 40, 0, 0]
Byte Value: 20
Next Byte Value: 30
Examples 2:
Output:
Original ByteBuffer: [20, 30, 0]
Byte Value: 0
since the buffer current position is incremented to greater than its limit
Exception throws : java.nio.BufferUnderflowException
get(int index)
The get(int index) method of ByteBuffer is used to read the article at a specified index.
Syntax :
public abstract byte get(int index)
Parameters: This method takes index (The index from which the Byte will be read) as a parameter.
Return Value: This method returns the Byte value at the given index.
Exception: This method throws
IndexOutOfBoundsException. If index is negative or not smaller than the buffer’s limit this exception is thrown.
Below are the examples to illustrate the
get(int index) method:
Examples 1:
Output:
Original ByteBuffer: [20, 30, 40]
Byte Value at index 0: 20
Byte Value at index 1: 30
Byte Value at index 2: 40
Examples 2:
