CharBuffer limit() methods in Java with Examples Last Updated : 23 Jul, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report 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: 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 CharBuffer // using allocate() method CharBuffer charBuffer = CharBuffer.allocate(4); // append char value in CharBuffer // using char() method charBuffer.append('a'); charBuffer.append('b'); // print the char buffer System.out.println("CharBuffer before " + "setting buffer's limit: " + Arrays.toString( charBuffer.array()) + "\nPosition: " + charBuffer.position() + "\nLimit: " + charBuffer.limit()); // Limit the CharBuffer // using limit() method charBuffer.limit(1); // print the char buffer System.out.println("CharBuffer before " + "setting buffer's limit: " + Arrays.toString( charBuffer.array()) + "\nPosition: " + charBuffer.position() + "\nLimit: " + charBuffer.limit()); } } Output: CharBuffer before setting buffer's limit: [a, b,, ] Position: 2 Limit: 4 CharBuffer after setting buffer's limit: [a, b,, ] 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 CharBuffer // using allocate() method CharBuffer charBuffer = CharBuffer.allocate(5); // append char value in CharBuffer // using char() method charBuffer.append('a'); charBuffer.append('b'); charBuffer.append('c'); // mark will be going to discarded by limit() charBuffer.mark(); // print the char buffer System.out.println("CharBuffer before " + "setting buffer's limit: " + Arrays.toString( charBuffer.array()) + "\nPosition: " + charBuffer.position() + "\nLimit: " + charBuffer.limit()); // Limit the charBuffer // using limit() method charBuffer.limit(4); // print the char buffer System.out.println("CharBuffer before " + "setting buffer's limit: " + Arrays.toString( charBuffer.array()) + "\nPosition: " + charBuffer.position() + "\nLimit: " + charBuffer.limit()); } } Output: CharBuffer before setting buffer's limit: [a, b, c,, ] Position: 3 Limit: 5 CharBuffer after setting buffer's limit: [a, b, c,, ] Position: 3 Limit: 4 Reference: https://docs.oracle.com/javase/9/docs/api/java/nio/CharBuffer.html#limit-int- Comment More infoAdvertise with us Next Article CharBuffer read() methods in Java with Examples R rohitprasad3 Follow Improve Article Tags : Java Java-Functions Java-CharBuffer Java-NIO package 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. 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 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 ByteBuffer limit() methods in Java with Examples 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: Thi 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 read() methods in Java with Examples The read() method of java.nio.CharBuffer Class is used to read characters into the specified character buffer. The buffer is used as a repository of characters as-is: the only changes made are the results of a put operation. No flipping or rewinding of the buffer is performed. Syntax: public int rea 4 min read CharBuffer flip() methods in Java with Examples The flip() method of java.nio.CharBuffer 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 2 min read Like
