getShort()
The
getShort() method of
java.nio.ByteBuffer class is used to read the next two bytes at this buffer's current position, composing them into a short value according to the current byte order, and then increments the position by two.
Syntax:
public abstract short getShort()
Return Value: This method returns the short value at the buffer's current position.
Throws: This method throws
BufferUnderflowException if there are fewer than four bytes remaining in this buffer.
Below are the examples to illustrate the getShort() method:
Examples 1:
Output:
Original ByteBuffer:
1034 1035 1036
Byte Value: 1034
Next Byte Value: 1035
Examples 2:
Output:
Original ByteBuffer:
1034 1036
Byte Value: 1034
Next Byte Value: 1036
there are fewer than two bytes remaining in this buffer
Exception Thrown : java.nio.BufferUnderflowException

getLong(int index)
The
getLong(int index) method of
ByteBuffer is used to read four bytes at the given index, composing them into a float value according to the current byte order.
Syntax:
public abstract long getLong(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 long 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
getLong(int index) method:
Examples 1:
Output:
Original ByteBuffer:
1034 1036
Byte Value: 1034
Next Byte Value: 1036
