A.x=10
B.x=20
C.x=6
D.编译不通过
[单选题]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; }
[单选题]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; }
[单选题]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.
[单选题]3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
[单选题]阅读下列程序: public class Test { public static void main (String args[]) { int x=3; for (int i=1;i<=10; i++) x=x+i/4; System. out. println(x);} }程序的输出结果是( )。A.12B.13C.14D.15
[单选题]执行如下程序: public class Test { public static void main (String args[]) { int x=1,a=0,b=0; switch (x) { case 0: b++; case 1: a++; case 2: a++;b++; } System.out.println("a=" +a ",b=" +b); } } 该程序的输出结果是( )。A.a=2,b=1B.a=1,b=1C.a=1,b=0D.a=2,b=2
[单选题]有如下程序 public class Test { int a,b; Test ( ) { a = 100; b = 200; } Test(int x, int y) { a = x; b = y; } public static void main(String args[]) { Test Obj1 = new Test(12,45); System.out.println("a = "Obj1.a+" b = "+ObB) ; Test Obj1 = new Test(); Sy
[单选题]以下程序输出结果为( )。 class test 2 { public static void main(String args[]) { int n=7; n<<=3; n=n&n+1 |n+2^n+3; n>>=2; System.out.println(n); } }A.0B.-1C.14D.64
[主观题]请阅读下面程序public class Test {public static void main (String[] args) {int i,j;for (i=1;i<5;i++) {for (j=1;j<=i;j++)system.out.print (i+"X"+j+"="+i*j+" ");System.out.println();}}}程序执行完后,i循环和j循环执行的次数分别是[ ]。
[主观题]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[ ]。
