The java.lang.Character.isLowSurrogate(char ch) is an inbuilt method in java which determines if the given char value is a Unicode low-surrogate code unit (also known as trailing-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.
public static boolean isLowSurrogate(char ch)
Parameters: The function accepts one mandatory parameter ch which specifies the character to be tested.
Return Value: The function returns a boolean value. The value returned is True if the char value is between MIN_LOW_SURROGATE and MAX_LOW_SURROGATE inclusive, False otherwise.
Below programs illustrate the Character.isLowSurrogate() method:
c1 is a Unicode low-surrogate ? true h is a Unicode low-surrogate ? false
c1 is a Unicode low-surrogate ? true x is a Unicode low-surrogate ? false
