ByteBuffer limit() methods in Java with Examples Last Updated : 19 Jan, 2023 Summarize Comments Improve Suggest changes Share Like Article Like Report The limit() method of java.nio.ByteBuffer Class is used to set this buffer's limit. If the position is larger than the new limit then it is set to the new limit. If the mark is defined and larger than the new limit then it is discarded. Syntax: public ByteBuffer limit(int newLimit) Return Value: This method returns this buffer. Below are the examples to illustrate the limit() method: Examples 1: Java // Java program to demonstrate // limit() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // defining and allocating ByteBuffer // using allocate() method ByteBuffer byteBuffer = ByteBuffer.allocate(4); // put byte value in byteBuffer // using put() method byteBuffer.put((byte)20); byteBuffer.put((byte)30); // print the byte buffer System.out.println("ByteBuffer before compact: " + Arrays.toString(byteBuffer.array()) + "\nPosition: " + byteBuffer.position() + "\nLimit: " + byteBuffer.limit()); // Limit the byteBuffer // using limit() method byteBuffer.limit(1); // print the byte buffer System.out.println("\nByteBuffer after compact: " + Arrays.toString(byteBuffer.array()) + "\nPosition: " + byteBuffer.position() + "\nLimit: " + byteBuffer.limit()); } } Output:ByteBuffer before compact: [20, 30, 0, 0] Position: 2 Limit: 4 ByteBuffer after compact: [20, 30, 0, 0] Position: 1 Limit: 1 Examples 2: Java // Java program to demonstrate // limit() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { // defining and allocating ByteBuffer // using allocate() method ByteBuffer byteBuffer = ByteBuffer.allocate(5); // put byte value in byteBuffer // using put() method byteBuffer.put((byte)20); byteBuffer.put((byte)30); byteBuffer.put((byte)40); // mark will be going to discarded by limit() byteBuffer.mark(); // print the byte buffer System.out.println("ByteBuffer before compact: " + Arrays.toString(byteBuffer.array()) + "\nPosition: " + byteBuffer.position() + "\nLimit: " + byteBuffer.limit()); // Limit the byteBuffer // using limit() method byteBuffer.limit(4); // print the byte buffer System.out.println("\nByteBuffer after compact: " + Arrays.toString(byteBuffer.array()) + "\nPosition: " + byteBuffer.position() + "\nLimit: " + byteBuffer.limit()); } } Output:ByteBuffer before compact: [20, 30, 40, 0, 0] Position: 3 Limit: 5 ByteBuffer after compact: [20, 30, 40, 0, 0] Position: 3 Limit: 4 Reference: https://docs.oracle.com/javase/9/docs/api/java/nio/ByteBuffer.html#limit-int- Comment More infoAdvertise with us Next Article ByteBuffer flip() methods in Java with Examples R rohitprasad3 Follow Improve Article Tags : Java Java-Functions Java-NIO package Java-ByteBuffer Practice Tags : Java Similar Reads Buffer limit() methods in Java with Examples The limit() method of java.nio.Buffer Class is used to set this buffer's limit.

Syntax: public Buffer limit(int newLimit) Return Value: This method 2 min read DoubleBuffer limit() methods in Java with Examples The limit() method of java.nio.DoubleBuffer Class is used to modify this DoubleBuffer'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 2 min read CharBuffer limit() methods in Java with Examples The limit() method of java.nio.CharBuffer Class is used to set this buffer's limit. If the position is larger than the new limit then it is set to the new limit. If the mark is defined and larger than the new limit then it is discarded. Syntax: public CharBuffer limit(int newLimit) Return Value: Thi 2 min read ByteBuffer get() method in Java with Examples 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 BufferUnderflow 6 min read ByteBuffer flip() methods in Java with Examples The flip() method of java.nio.ByteBuffer Class is used to flip this buffer. The limit is set to the current position and then the position is set to zero. If the mark is defined then it is discarded. After a sequence of channel-read or put operations, invoke this method to prepare for a sequence of 3 min read ByteBuffer wrap() methods in Java with Examples wrap(byte[] array) The wrap() method of java.nio.ByteBuffer Class is used to wraps a byte array into a buffer. The new buffer will be backed by the given byte array, i.e., modifications to the buffer will cause the array to be modified and vice versa. The new buffer's capacity and limit will be arra 4 min read Like
