IntBuffer limit() method in Java with Examples

The limit() method of java.nio.IntBuffer Class is used to modify this IntBuffer’s limit. This method takes the limit to be set as the parameter and sets that as the new limit of this Buffer. If the mark of this Buffer is already defined and is larger than the new specified limit, then this new limit is not set and discarded.

Syntax:

public final IntBuffer limit(int newLimit)

Parameter: The method takes one parameter newLimit of integer type which refers to the limit that is to be set as the new limit of the buffer.



Return Value: This method returns this buffer after setting the specified new limit as the new limit of this Buffer.

Below are the examples to illustrate the limit() method:

            + "\nLimit: "
            + intBuffer.limit());
    }
}

Output:

IntBuffer before setting buffer's limit: [20, 30, 0, 0]
Position: 2
Limit: 4

intBuffer after setting buffer's limit: [20, 30, 0, 0]
Position: 1
Limit: 1
