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:
import java.lang.*;
public class gfg {
public static void main(String[] args)
{
char c1 = '\u0a4f' , c2 = '\ud8b4' ;
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:
import java.lang.*;
public class gfg {
public static void main(String[] args)
{
char c1 = '\u0b9f' , c2 = '\ud5d5' ;
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
