Java Character lowSurrogate() Method

The lowSurrogate(int codePoint) method of Character class returns the trailing surrogate code unit which is used for the representation of the character in the UTF-16 encoding. On the other hand, if the specified character is not a supplementary character, an unspecified char is returned.

If the method isSupplementaryCodePoint (x) is true, the method isLowSurrogate(lowSurrogate(x)) and the method toCodePoint(highSurrogate(x), lowSurrogate(x))==x are also true.

Syntax

Parameter

The above method requires only one parameter:

a.) The codePoint which is the character that needs to be tested.

Return Value

The lowSurrogate(int codePoint) method returns the trailing code unit which is used as the representation of the character in the UTF-16 encoding.

Example 1

public class JavaCharacterlowSurrogateExample1 {
	public static void main(String[] args) {
	    // Initialize three codepoints: cp1, cp2 and cp3.
		int cp1 = 65;
		int cp2 = 152;
             int cp3 = 567;
	    // Find the current surrogate codePoint.
		char result1 = Character.lowSurrogate(cp1);
		char result2 = Character.lowSurrogate(cp2);
             char result3 = Character.lowSurrogate(cp3);
	    // Print the result.
System.out.println("The current surrogate code unit for the character"+ cp1 +" is:"+ result1);
System.out.println("The current surrogate code unit for the character"+ cp2 +" is:"+ result2);
System.out.println("The current surrogate code unit for the character"+ cp3 +" is:"+ result3);
        }
}

Test it Now

Output:

The current surrogate code unit for the character65 is:?
The current surrogate code unit for the character152 is:?
The current surrogate code unit for the character567 is:?

Example 2

public class JavaCharacterlowSurrogateExample2 {
public static void main(String[] args) {
        // Initialize three codepoints: cp1, cp2 and cp3
	 int cp1 = 49;
                int cp2 = 121;
                int cp3 = 2342;
     // Check whether the codepoints are current surrogate code units or not.
	        char check1 = Character.lowSurrogate(cp1);
                      char check2 = Character.lowSurrogate(cp2);
                      char check3 = Character.lowSurrogate(cp3);
        // Print the result.
	if(check1==3F){
	   System.out.print("The codepoint \'"+cp1+"\' is not a current surrogate code unit.\n");
		}
	else{
  	   System.out.print("The codePoint \'"+cp1+"\' is a current surrogate code unit.\n");
		}
                
	  if(check2==3F){
	      System.out.print("The codepoint \'"+cp2+"\' is not a current surrogate code unit.\n");
		}
	  else{
	     System.out.print("The codePoint \'"+cp2+"\' is a current surrogate code unit.\n");
		}
                
               if(check3==3F){
	     System.out.print("The codepoint \'"+cp3+"\' is not a  current surrogate code unit.\n");
		}
	 else{
	     System.out.print("The codePoint \'"+cp3+"\' is a current surrogate code unit.\n");
         	        }
         }
}

Test it Now

Output:

The codePoint '49' is a current surrogate code unit.
The codePoint '121' is a current surrogate code unit.
The codePoint '2342' is a current surrogate code unit.
