线程*主要异常* java.util.InputMismatchException

Question

package Myth; 

import java.util.Scanner; 

public class Practice 

{ 

    public static void heightEstimator(double momH, double dadH) 
    { 
     Scanner kb= new Scanner(System.in); 
     System.out.println("Enter your Mothers Height in Feet: "); 
     momH= kb.nextInt(); 
     System.out.println("Enter your Fathers Height in Feet: "); 
     dadH= kb.nextInt(); 
     double w= (dadH+momH)/2; 
     System.out.println("You will be "+ w+ "Ft.");  
    } 

    public static int shoeSize(double x) 
    { 
     Scanner z= new Scanner(System.in); 
     System.out.println("Enter your Fathers Heigh in Inches: "); 
     x= z.nextInt(); 
     double y= x/6; 
     System.out.println("Your shoe size will be: "+ y); 
     return 0;   
    } 
    public static void main(String[] args) 
    { 
     heightEstimator(0, 0); 
     shoeSize(0); 
    } 


} 

我不知道为什么我一直在我的代码中得到这个错误。我的代码有什么问题？

Answer 1

momH = kb.nextInt（）;是错误的，因为datatytpe“momH”和“dadH”和“x”是一个双数据类型，而不是整数。

你应该改变nextInt（）来nextDouble（）;
