Java Character highSurrogate() Method

The highSurrogate(intcodePoint) method of Character class generally returns the current surrogate codePoint for the given surrogate pair which indicates the supplementary character in the UTF encoding. If the given character is not specified(or valid), an unspecified char is returned.

Syntax

Parameter

codePoint: It is a supplementary character that needs to be tested.

Return Value

The highSurrogate(intcodePoint)method of Character class returns the current surrogate code unit which is used to indicate the character in the UTF-16 encoding.

Example 1

public class JavaCharacterhighSurrogateExample1 {	
public static void main(String[] args) {
// Initialize the codePoints.
	int codepoint1 = 6587;
	int codepoint2 = 67324;
// Get the leading surrogate 
	char result1 = Character.highSurrogate(codepoint1);
	char result2 = Character.highSurrogate(codepoint2);
// Print the result.
System.out.println("The leading surrogate for the codePoint "+codepoint1 +" is given as:"+result1);
System.out.println("The leading surrogate for the codePoint "+codepoint2 +" is given as:"+result2);
	}
}

Output:

The leading surrogate for the codePoint 6587 is given as:?
The leading surrogate for the codePoint 67324 is given as:?

Example 2

public class JavaCharacterhighSurrogategetTypeExample2 {
	public static void main(String args[])
	 {
	System.out.println("The integer value for the character 2 is given as:");  	
	System.out.println(Character.highSurrogate('2'));
	System.out.println("The integer value for the character { is given as:");  	
	System.out.println(Character.highSurrogate('{'));  	
	System.out.println("The integer value for the character * is given as:");  	
	System.out.println(Character.highSurrogate('*')); 
	System.out.println("The integer value for the character @ is given as:");  	
	System.out.println(Character.highSurrogate('@'));     
	System.out.println("The integer value for the character $ is given as:");  	
	System.out.println(Character.highSurrogate('$'));  
	 }

Output:

The integer value for the character 2 is given as:
?
The integer value for the character { is given as:
?
The integer value for the character * is given as:
?
The integer value for the character @ is given as:
?
The integer value for the character $ is given as:
?
