给出下列代码的输出结果：public class E{public static void main(String args[]){System.out.println((int)'a');}}
举一反三
- 给出下列【代码】注释标注的代码的输出结果。________ public class E { public static void main(String args[]){ int [] a ={1,2,3,4,5,6}; System.out.println(a.length+"hello"+a[5]); //【代码】 } }
- 下列ABCD注释标注的哪行代码有错public class Demo { public static void main(String args[]) { System.out.println("Java"); system.out.println("hello"); System.out.println("你好"); } } A: public class Demo B: public static void main(String args[]) C: system.out.println("ok"); D: System.out.println("您好");
- 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”) ; } }
- 以下代码的输出结果 ? public class Test1{ static int x = 3; static { ++x; } public static void main(String args[]){ System.out.println(x); } static { x++; } }
- 阅读以下代码: public class foo{ public static void main (String[] args){ String s; System.out.println("s=" + s); 输出结果应该是
