Java Character highSurrogate()用法及代码示例

Character 类的 highSurrogate(intcodePoint) 方法通常返回给定代理对的当前代理 codePoint，它表示 UTF 编码中的补充字符。如果未指定(或有效)给定字符，则返回未指定的字符。

用法

public static char highSurrogate(int codePoint)

参数

codePoint: 是需要测试的补充字符。

返回值

Character 类的 highSurrogate(intcodePoint) 方法返回当前的代理代码单元，用于指示 UTF-16 编码中的字符。

例子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);
	}
}

输出：

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

例子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('$'));  
	 }

输出：

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:
?
