Java String intern() 方法示例。
java 8object oriented programmingprogramming
String 类的 intern()方法返回字符串对象的规范表示。因此,对于任意两个字符串 s 和 t,当且仅当 s.equals(t) 为真时,s.intern() == t.intern() 才为真。
示例
import java.io.*; public class Test { public static void main(String args[]) { String Str1 = new String("Welcome to Tutorialspoint.com"); String Str2 = new String("WELCOME TO SUTORIALSPOINT.COM"); System.out.print("Canonical representation:" ); System.out.println(Str1.intern()); System.out.print("Canonical representation:" ); System.out.println(Str2.intern()); } }
输出
Canonical representation: Welcome to Tutorialspoint.com Canonical representation: WELCOME TO SUTORIALSPOINT.COM
