若有如下程序:public class Test {public static void main (String[] args) {int x=20;if (x>10) System.out.print(x-=5);if (x>5) System.out.print(x--);}}则程序运行后的输出结果是【 】。

下面程序段的输出结果为 package test; public class ClassA { int x=20; static int y=6; public static void main(String args[]) { ClassB b=new ClassB(); b.go(10); System.out.println("x="+b.x); } } class ClassB { int x; void go(int y) { ClassA a=new ClassA(); x=a.y; } }A.x=10B.x=20C.x=6D.编译不通过

interface A{int x = 0;}class B{int x =1;}class C extends B implements A {public void pX(){System.out.println(x);}public static void main(String[] args) {new C().pX();}}

下面程序段的输出结果为( )。 package test; public class ClassA { int x=20: static int y=6; public static void main(String args[]) { ClassB b=new ClassB; go(10); System.out.println("x="+b.x); } } class ClassB { int X; void go(int y) { ClassA a=new ClassA; x=a.Y ; } }A.x=10B.x=20C.x=6D.编译不通过

下面程序段的输出结果为 package test; public class A { int x=20; static int y=6; public static void main(String args[]) { Class B b=new Class B(); b.go(10); System.out.println(”x=”+b.x); } } class Class B { int x; void go(int y) { ClassA a=new ClassA(); x=a.y; } }A.x=10B.x=20C.x=6D.编译不通过

有以下源程序: package test; public class ClassA { int x=20; static int y=6; public static void main(String args[]) { ClassB b=new ClassB(); b.go(10); System.out.println("x="+b.x); } } class ClassB { int x; void go(int y) { ClassA a=new ClassA(); x=a.y; } } 上述源程序文件的运行结果为( )。A.x=10B.x=20C.x=6D.编译不通过
