Character.isHighSurrogate() method in Java with examples
The java.lang.Character.isHighSurrogate() is a inbuilt method in java which determines if the given char value is a Unicode high-surrogate code unit (also known as leading-surrogate code unit). Such values do not represent characters by themselves but are used in the representation of supplementary characters in the UTF-16 encoding.
Syntax:
public static boolean isHighSurrogate(char ch)
Parameters: The function accepts a single mandatory parameter ch which specifies the value to be tested.
Return Value: The function returns a boolean value. The value returned is True if the char value is between MIN_HIGH_SURROGATE and MAX_HIGH_SURROGATE inclusive, False otherwise.
Below programs illustrate the Character.isHighSurrogate() method:
Program 1:
// Java program to illustrate the // Character.isHighSurrogate() method import java.lang.*; public class gfg { public static void main(String[] args) { // create 2 char primitives c1, c2 char c1 = '\u0a4f' , c2 = '\ud8b4' ; // assign isHighSurrogate results of // c1, c2 to boolean primitives bool1, bool2 boolean bool1 = Character.isHighSurrogate(c1); System.out.println( "c1 is a Unicode" + "high-surrogate code unit ? " + bool1); boolean bool2 = Character.isHighSurrogate(c2); System.out.println( "c2 is a Unicode" + "high-surrogate code unit ? " + bool2); } } |
Output:
c1 is a Unicodehigh-surrogate code unit ? false c2 is a Unicodehigh-surrogate code unit ? true
Program 2:
// Java program to illustrate the // Character.isHighSurrogate() method import java.lang.*; public class gfg { public static void main(String[] args) { // create 2 char primitives c1, c2 char c1 = '\u0b9f' , c2 = '\ud5d5' ; // assign isHighSurrogate results of // c1, c2 to boolean primitives bool1, bool2 boolean bool1 = Character.isHighSurrogate(c1); System.out.println( "c1 is a Unicode" + "high-surrogate code unit ? " + bool1); boolean bool2 = Character.isHighSurrogate(c2); System.out.println( "c2 is a Unicode" + "high-surrogate code unit ? " + bool2); } } |
Output:
c1 is a Unicodehigh-surrogate code unit ? false c2 is a Unicodehigh-surrogate code unit ? false
