LongBuffer limit() method in Java with Examples

The limit() method of java.nio.LongBuffer Class is used to modify this LongBuffer’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 LongBuffer 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:

        // print the long buffer
        System.out.println(
            "\nLongBuffer after "

            + "\nPosition: "
            + longBuffer.position()
            + "\nLimit: "
            + longBuffer.limit());
    }
}

Output:

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

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