ByteBuffer reset() methods in Java with Examples Last Updated : 16 Jul, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The reset() method of java.nio.ByteBuffer Class is used to reset this buffer's position to the previously-marked position. Invoking this method neither changes nor discards the mark's value. Syntax: public ByteBuffer reset() Return Value: This method returns this buffer. Below are the examples to illustrate the reset() method: Examples 1: Java // Java program to demonstrate // reset() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { try { byte[] barr = { 10, 20, 30, 40 }; // creating object of ByteBuffer // and allocating size capacity ByteBuffer bb = ByteBuffer.wrap(barr); // try to set the position at index 2 bb.position(2); // Set this buffer mark position // using mark() method bb.mark(); // try to set the position at index 4 bb.position(4); // display position System.out.println("position before reset: " + bb.position()); // try to call reset() to restore // to the position we marked bb.reset(); // display position System.out.println("position after reset: " + bb.position()); } catch (InvalidMarkException e) { System.out.println("new position is less than " + "the position we marked before "); System.out.println("Exception throws: " + e); } } } Output: position before reset: 4 position after reset: 2 Examples 2: Java // Java program to demonstrate // reset() method import java.nio.*; import java.util.*; public class GFG { public static void main(String[] args) { try { byte[] barr = { 10, 20, 30, 40 }; // creating object of ByteBuffer // and allocating size capacity ByteBuffer bb = ByteBuffer.wrap(barr); // try to set the position at index 2 bb.position(2); // Set this buffer mark position // using mark() method bb.mark(); // try to set the position at index 4 bb.position(1); // display position System.out.println("position before reset: " + bb.position()); // try to call reset() to restore // to the position we marked bb.reset(); // display position System.out.println("position after reset: " + bb.position()); } catch (InvalidMarkException e) { System.out.println("\nnew position is less than " + "the position we marked before "); System.out.println("Exception throws: " + e); } } } Output: position before reset: 1 new position is less than the position we marked before Exception throws: java.nio.InvalidMarkException Reference: https://docs.oracle.com/javase/9/docs/api/java/nio/ByteBuffer.html#reset-- Comment More infoAdvertise with us Next Article Buffer reset() 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 reset() methods in Java with Examples The reset() method of java.nio.Buffer Class is used to reset this buffer's position to the previously-marked position.
