下面代码的输出结果是
String tenCharString = "AAAAAAAAAA";
System.out.println(tenCharString.replace("AAA","KKK"));
String tenCharString = "AAAAAAAAAA";
System.out.println(tenCharString.replace("AAA","KKK"));
举一反三
- 下面代码的输出结果是0。 String s = new String(); System.out.println(s.length());
- 下列代码段的输出结果是（ ） s=20; if(s>30) System.out.println(‘’AAA``); System.out.println(``BBB``); A: AAA B: BBB C: AAA BBB D: 什么也不显示
- 中国大学MOOC: 下列代码中构造方法的返回类型是（）public class Village { Village () { System .out .println(“hiding in Village”) ; } public static void main( String args [ ]) { Village c =new Village ( ) ;}class Village { public static void main( String args [ ]) { Village c =new Village ( ) ; } Village () { System .out .println(“hiding in Village”) ; } }
- （2-5）下面程序段的输出结果是。String s0 = new String("hello,中国!");System.out.println(s0.length());
- 顺序执行下面2个语句，输出的结果是 。 String s="hello!"; System.out.println(s.length());
