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:
Output:
c1 is a Unicodehigh-surrogate code unit ? false
c2 is a Unicodehigh-surrogate code unit ? true
Program 2:
