Question

以下程序包含9个错误。更正错误并提交程序的有效版本。程序的更正版本应产生以下输出：

x = 10.01和y = 8.0 x = 10.01和y = 867.5309 来自main的值是：867.5309 z = 5

我已经对此进行了一些更改，但是我可以弄清楚为什么未调用x和y的原因。

public class Oops3 {
    public static void main(String[] args) {
        double y = 867.5309;
        double x = 10.01;
        printer(double x, double y);
        printer(x);
        printer(y);
        System.out.println("z = " + z);
}

public static void printer(double x, double y) {
    int z = 5;
    System.out.println("x = " + double x + " and y = " + double y);
    System.out.println("The value from main is: " + y);
}

}

Answer 1

尝试以下操作：（不确定您已经进行了多少更改）

public class Oops3 {

public static void printer(double x, double y) {
        System.out.println("x = " +  x + " and y = " +  y);
        System.out.println("The value from main is: " + y);}

public static void main(String[] args) {

            int z = 5;
            double y = 867.5309;
            double x = 10.01;
            System.out.println("x= " + x + " and y = 8.0");
            printer( x,y);
            System.out.println("z = " + z);

}}

Answer 2

以下是您要查找的工作代码

public class Oops3 
{
public static void printer(double x, double y, int z) {
    System.out.println("x = " + x + " and y = " + y);
System.out.println("The value from main is: " + y);
    System.out.println("z = " + z);
}

public static void main(String[] args) {
    Oops3 O=new Oops3();
    double y = 867.5309;
    double x = 10.01;
int z = 5;
    O.printer(x, y, z);
}
}

Answer 3

这段代码对我有用

public class Oops3 {
public static void main(String [] args) {
    Oops3 i = new Oops3();
    double bubble = 867.5309;
    double x = 10.01;
    double y = 8.0;
    int z = 5;
    i.printer(x, y);
    i.printer(x, bubble);
    System.out.println("The value from main is: " + bubble);
    System.out.println("z = " + z);
}

public static void printer(double x, double y) {
    System.out.println("x = " +  x + " and y = " + y);
}
}
