public static void main(String[] args) { String s1="123"; String s2 = "123"; System.out.println(s1==s2); } 输出的结果是________
举一反三
- public class Test { public static void main(String[] args) { String s1 = "abc"; String s2 = new String ("abc"); System.out.println(s1 == s2); } } 程序运行结果是
- 下列程序的输出结果是（ ） class StringDemo{ public static void main(String[] args){ String s1 = “a”; String s2 = “b”; show(s1,s2); System.out.println(s1+s2); } public static void show(String s1,String s2){ s1 = s1 +“q”; s2 = s2 + s1; } } A: a B: aq C: aqbaq D: aqaq
- 以下程序的输出结果是 String s1="1",s2="2"; String s=s1+s2; System.out.println(s);
- 下面哪个结果是正确的？（） public class Testjava{ public static void main(String[] args){ String s= "abcd"; String s1,s2; s1 =s.concat("e"); s2 = s1.replace('c','e'); System.out.println(s2); } } A: Abcde B: Abced C: Abede D: Abc
- 下列语句输出结果为( )。public class test{public static void main(String args []){String s1=new String("How");String s2=new String("How");System.out. println(!(s1 ==s2));} A: false B: true C: 1 D: 0
