getChar()
The
getChar() method of
java.nio.ByteBuffer class is used to get method for reading a char value
Reads the next two bytes at this buffer's current position, composing them into a char value according to the current byte order, and then increments the position by two.
Syntax:
public abstract char getChar()
Return Value: This method returns the char value 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 getChar() method:
Examples 1:
Output:
Original ByteBuffer:
G e e k s
Byte Value: G
Next Byte Value: e
Examples 2:
Output:
Original ByteBuffer: a b c
First char Value: a
Second char Value: b
Third char Value: c
since the buffer current position is incremented to greater than its limit
Exception Thrown: java.nio.BufferUnderflowException
get(int index)
The get(int index) method of ByteBuffer is used to reads two bytes at the given index, composing them into a char value according to the current byte order.
Syntax:
public abstract char getChar(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 char 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: a b c
char Value at index 0: a
char Value at index 2: b
char Value at index 4: c
Examples 2:
