这个 JAVA朗,性格。Ishighrogate() 是java中的一种内置方法,用于确定给定的字符值是否为Unicode高级代理代码单元(也称为前导代理代码单元)。这些值本身并不表示字符,而是用于表示UTF-16编码中的补充字符。
null
语法:
public static boolean isHighSurrogate(char ch)
参数: 该函数只接受一个强制参数 中国 它指定了要测试的值。
返回值: 该函数返回一个布尔值。返回的值为 符合事实的 如果char值介于MIN_HIGH_subrogate和MAX_HIGH_subrogate(含)之间, 错误的 否则
下面的程序说明了这个角色。isHighSurrogate()方法:
项目1:
// Java program to illustrate the // Character.isHighSurrogate() method import java.lang.*; public class gfg { public static void main(String[] args) { // create 2 char primitives c1, c2 char c1 = 'u0a4f' , c2 = 'ud8b4' ; // assign isHighSurrogate results of // c1, c2 to boolean primitives bool1, bool2 boolean bool1 = Character.isHighSurrogate(c1); System.out.println( "c1 is a Unicode" + "high-surrogate code unit ? " + bool1); boolean bool2 = Character.isHighSurrogate(c2); System.out.println( "c2 is a Unicode" + "high-surrogate code unit ? " + bool2); } } |
输出:
c1 is a Unicodehigh-surrogate code unit ? false c2 is a Unicodehigh-surrogate code unit ? true
项目2:
// Java program to illustrate the // Character.isHighSurrogate() method import java.lang.*; public class gfg { public static void main(String[] args) { // create 2 char primitives c1, c2 char c1 = 'u0b9f' , c2 = 'ud5d5' ; // assign isHighSurrogate results of // c1, c2 to boolean primitives bool1, bool2 boolean bool1 = Character.isHighSurrogate(c1); System.out.println( "c1 is a Unicode" + "high-surrogate code unit ? " + bool1); boolean bool2 = Character.isHighSurrogate(c2); System.out.println( "c2 is a Unicode" + "high-surrogate code unit ? " + bool2); } } |
输出:
c1 is a Unicodehigh-surrogate code unit ? false c2 is a Unicodehigh-surrogate code unit ? false
