Buffer limit() methods in Java with Examples Last Updated : 16 Jul, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The limit() method of java.nio.Buffer 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 Buffer 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); // Typecast byteBuffer to buffer Buffer buffer = (Buffer)byteBuffer; // print the byte buffer System.out.println("Buffer before operation: " + Arrays.toString( (byte[])buffer.array()) + "\nPosition: " + buffer.position() + "\nLimit: " + buffer.limit()); // Limit the Buffer // using limit() method buffer.limit(1); // print the buffer System.out.println("\nBuffer after operation: " + Arrays.toString( (byte[])buffer.array()) + "\nPosition: " + buffer.position() + "\nLimit: " + buffer.limit()); } } Output: Buffer before operation: [20, 30, 0, 0] Position: 2 Limit: 4 Buffer after operation: [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); // Typecast byteBuffer to buffer Buffer buffer = (Buffer)byteBuffer; // mark will be going to discarded by limit() buffer.mark(); // print the buffer System.out.println("Buffer before operation: " + Arrays.toString( (byte[])buffer.array()) + "\nPosition: " + buffer.position() + "\nLimit: " + buffer.limit()); // Limit the Buffer // using limit() method buffer.limit(4); // print the buffer System.out.println("\nBuffer after operation: " + Arrays.toString( (byte[])buffer.array()) + "\nPosition: " + buffer.position() + "\nLimit: " + buffer.limit()); } } Output: Buffer before operation: [20, 30, 40, 0, 0] Position: 3 Limit: 5 Buffer after operation: [20, 30, 40, 0, 0] Position: 3 Limit: 4 Reference: https://docs.oracle.com/javase/9/docs/api/java/nio/Buffer.html#limit-int- Comment More infoAdvertise with us Next Article CharBuffer length() methods in Java with Examples R rohitprasad3 Follow Improve Article Tags : Java Java-Functions Java-NIO package Java-Buffer Practice Tags : Java Similar Reads 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 Buffer mark() methods in Java with Examples The mark() method of java.nio.Buffer Class is used to set this buffer's mark at its position.Syntax: public Buffer mark() Return Value: This method returns this buffer.Below are the examples to illustrate the mark() method:Examples 1: Java // Java program to demonstrate // mark() method import java. 2 min read CharBuffer length() methods in Java with Examples The length() method of java.nio.CharBuffer Class is used to return the length of this character buffer. When viewed as a character sequence, the length of a character buffer is simply the number of characters between the position (inclusive) and the limit (exclusive); that is, it is equivalent to re 2 min read Buffer 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.
