String s=new String(“hello”);String t =new String(“hello”);char c [ ] ={‘h’,’e’,’l’,’l’,’o’};下列哪些表达式返回true ?
A: s.equals(t);
B: t.equals(c);
C: s= =t ;
D: t.equals (new String(“hello”));
A: s.equals(t);
B: t.equals(c);
C: s= =t ;
D: t.equals (new String(“hello”));
举一反三
- String s= "hello"; String t = "hello"; char c[] = {’h’,’e’,’l’,’l’,’o’} ; Which return true?() A: s.equals(t); B: t.equals(c); C: s==t; D: t.equals(new String("hello")); E: t==c;
- 给出下面的代码String s= "hello";String t = "hello";char c[] = {'h','e','l','l','o'};下列选项里,哪些返回true? [] A: s.equals(t); B: t.equals(c); C: s==t; D: t.equals(new String("hello")); E: t==c;
- String s=new String(“hello”); String t =new String(“hello”); char c [ ] ={‘h’,’e’,’l’,’l’,’o’}; 下列哪些表达式返回true ?
- 若String s = “Hello” ; String t = “Hello”;String c=new String(s);则下列哪个表达式返回false?( ) A: s.equals(t); B: t.equals(c); C: s==c; D: s==t;
- String s=”hello”;String t=”hello”;String e=new String(”hello”) ;char c[]={„h‟,e‟,‟l‟,‟l‟,o‟};给定如上Java代码,编译运行时,以下( )语句的值是true。 A: s.equals(t) B: t.equals(c) C: t== e D: t==c
