当我创建方法时，我的Java代码正在显示编译器错误

Question

package aj;
import java.util.Scanner;
public class ConvertingNumber {
    public static void main(String[] args) {
        Scanner a = new Scanner(System.in);
        System.out.println("Enter the Number");
        int num = a.nextInt();
        System.out.println("Enter the base for the given number");
        int base = a.nextInt();
        converting(num,base);
        public static int converting(int num , int base) {
            String sum="";
            while(num > 0) {
                int rem = 0;
                rem = num % base;
                num = num / base;
                sum = rem + sum;
            }
            System.out.println(sum);
        }   
    }
}

对于我的上述Java代码，正在获取Compier错误说：

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
The method converting(int, int) is undefined for the type ConvertingNumber
void is an invalid type for the variable converting
Syntax error on token "(", ; expected
Duplicate local variable num
Syntax error on token ",", ; expected
Duplicate local variable base
Syntax error on token ")", ; expected
at aj.ConvertingNumber.main(ConvertingNumber.java:12)

请任何人帮助我解决这个问题。预先感谢。

Answer 1

converting方法应与主要方法相位

package aj;
import java.util.Scanner;
public class ConvertingNumber {
    public static void main(String[] args) {
        Scanner a=new Scanner(System.in);
        System.out.println("Enter  the Number");
        int num=a.nextInt();
        System.out.println("enter the base for the given number");
        int base=a.nextInt();
        converting(num,base);
    }
    //This method should be out side the main method
    public static void converting(int num , int base) {
        String sum="";
        while(num>0) {
            int rem=0;
            rem=num%base;
            num=num/base;
            sum=rem+sum;
        }
        System.out.println(sum);
    }   
}

我已更正您的代码。

package aj;
import java.util.Scanner;
public class ConvertingNumber  {
public static void main(String[] args) {
    Scanner a=new Scanner(System.in);
    System.out.println("Enter  the Number");
    int num=a.nextInt();
    System.out.println("enter the base for the given number");
    int base=a.nextInt();
    ConvertingNumber .converting(num,base); 
           //converting(num,base);
}
    public static int converting(int num , int base)
    {
        int sum=0;
        while(num>0)
        {
            int rem=0;
            rem=num%base;
            num=num/base;
            sum=rem+sum;
        }
        //System.out.println(sum);
        return sum;
        } 

}
