【单选题】以下代码的输出结果为（）public class Pass{ static int j = 20;

public class Pass{
static int j = 20;
public void amethod(int x){
x = x*2;
j = j*2;
}
public static void main(String args]){
int i = 10;
Pass p = new Pass();
p.amethod(i);
System.out.println(i+" and "+j);
}
}

选项： A:

错误:方法参数与变量不匹配

B:

20 and 40

C:

10 and 40

D:

10 and 20

}

错误:方法参数与变量不匹配

20 and 40

10 and 40

10 and 20

public class Pass{

static int j = 20;

public void amethod(int x){

x = x*2;

j = j*2;

}

public static void main(String args]){

int i = 10;

Pass p = new Pass();

p.amethod(i);

System.out.println(i+" and "+j);

}

错误:方法参数与变量不匹配

20 and 40

10 and 40

10 and 20

17.写出程序运行结果：public class Test{ public static void leftshift(int i, int j){ i+=j; } public static void main(String args[]){ int i = 4, j = 2; leftshift(i, j); System.out.println(i); } }

18. public class OneOuterClass { private int i = 10; private int j = 20; private class OneInnerClass{ private int i= 30; public void print(){ System.out.println("Sum:i+j="+(i+j) ); } } public static void main(String[] args) { newZjOuterClass().new ZjInnerClass().print(); } } 输出结果是：

19.写出以下程序运行结果__、__、__。public class Demo7 { public static void main(String[] args) { int i=1,j=0; int x=2; while(x<13) { for(;;) { if(i*j>10) break; i++;

20.下面程序的输出结果是什么？public class cs6{public static void main(String args[]){ int i =1; int j =10; do{ if(i++

21.下面代码运行后输出结果是（）。public class Test{ public static void main(String[] args){ A obj = new A(); System.out.println(obj.i); }}class A{ int i = 6; public A(){ this(10); } public A(int j){ i = j; }}选项： A:10; B:程序编译错误; C:0; D:6
