修复程序上的错误以调用 Java 中的方法

Question

以下程序包含 9 个错误。更正错误并提交程序的工作版本。该程序的更正版本应产生以下输出：

x = 10.01 and y = 8.0 x = 10.01 and y = 867.5309 来自 main 的值为：867.5309 z = 5

我已经对此做了一些更改，但我可以弄清楚为什么没有调用 x 和 y。

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

试试这个：（不确定你已经做了多少改变）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);}}
