智慧职教: public class Foo{ int i; static String s; void imethod(){ } static void smethod(){ }}已知f是Foo的一个实例，下面语句是否正确？Foo.imethod()
举一反三
- 读代码: public class Test { public static void main (String args[]) { class Foo { public int i = 3; } Object o = (Object) new Foo(); Foo foo = (Foo)o; System.out.println(foo.i); } } 结果是：
- 读代码:public class foo {static String s;public static void main (String[]args) {System.out.println (“s=” + s);}}结果是
- 关于下列代码说法正确的是( ) public class Foo{ public int add(int a,int b){ return a+b; } public static void main(String[] args){ Foo foo = null; System.out.println(foo.add(10,20)); } }
- 下面代码的运行结果为：（ ） import java.io.*; import java.util.*; public class foo{ public static void main (String[] args){ String s; System.out.println("s=" + s); } }
- 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
