Java Character isHighSurrogate() Method

The isHighSurrogate(char ch) method of Character class determines whether the given value is high-surrogate code unit, which is also called a leading surrogate code unit.

These values cannot be used to represent the characters by themselves, but they can be used in the representation of supplementary characters in the UTF-16 encoding.

Syntax

Parameter

The above method requires only one parameter:

a.)The character value that needs to be tested.

Return Value

The isHighSurrogate(char ch) method returns a boolean value, i.e., true if the value of the character lies in between MIN_HIGH_SURROGATE and MAX_HIGH_SURROGATE. Otherwise, this method returns false.

Example 1

public class JavaCharacterisHighSurrogateExample1 {
	public static void main(String[] args) {
	  // Initialize the characters that need to be tested.
		char c1 = '\ud800';
		char c2 = '\uc71f';
		char c3 = '\u1016';	
	// Check the individual character whether it is 
		boolean result1 = Character.isHighSurrogate(c1);
		boolean result2 = Character.isHighSurrogate(c2);
		boolean result3 = Character.isHighSurrogate(c3);
	// print the result
System.out.println("The first character is a Unicode high-surrogate code unit: "+  result1);
System.out.println("The second character is a Unicode high-surrogate code unit: "+  result2);	
System.out.println("The third character is a Unicode high-surrogate code unit: "+  result3);	
	}
}

Test it Now

Output:

The first character is a Unicode high-surrogate code unit: true
The second character is a Unicode high-surrogate code unit: false
The third character is a Unicode high-surrogate code unit: false

Example 2

public class JavaCharacterisHighSurrogateExample2 {
	public static void main(String args[])
	{
   //Initialize two char value
	  char a1 ='Z';
	  char a2 ='z';
  //Create two object obj1 and obj2.
	  Character obj1 =new Character(a1);   
	  Character obj2 =new Character(a2);   
  //Check whether the given charactesr 'obj' and 'obj2' are isHighSurrogate or not.
	  boolean b1 = obj1.isHighSurrogate(a1);  
	  boolean b2 = obj2.isHighSurrogate(a2);  
  //Print the values.
	  System.err.println("The character 'Z' is a Unicode high-surrogate code unit: "+b1);        
	  System.err.println("The character 'z' is a Unicode high-surrogate code unit: "+b2);        
     }
}

Test it Now

Output:

The character 'Z' is a Unicode high-surrogate code unit: false
The character 'z' is a Unicode high-surrogate code unit: false
