Can't find array value-CodePudding

Can someone help me with this problem.

I have been given to do some coding exercise

I need to do search Array problem Below is the output that i want :

I have a problem where when I put the correct value it will not come out the output I want instead it will come out the output "Player not Found" so how to solve this. I feel like I missed something.

Here my code:

import java.util.Scanner;

public class Main{
    public static void main(String[]args){
    Scanner sc=new Scanner(System.in);
       
       System.out.println(" Welcome to VictoRoar Information System " );
       System.out.println( " ********************");
       
       System.out.print(" Enter n , number of player: ");
       int n = sc.nextInt();
       //declare,initialize array 
       String [] name = new String[n];
       double [] height = new double[n];
       sc.nextLine();
       
       //put input in the array 
       for (int i=0; i<n;i  )
       {
       System.out.print(" Enter player's name :" );
       name[i] = sc.nextLine();
       System.out.print(" Enter player's height (cm) :" );
       height[i] = sc.nextLine();
       }
       
       //search array
       System.out.print(" Write the player height that you want to know : ");
       double findheight=sc.nextDouble();
       boolean noheight = false;
        for(int i = 0; i<n; i  )
       { 
          if (n == height[i])
       {
          noheight = true;
          System.out.println("Player name "  name[i]   " with height "   height[i]  " present at index "  i);
       }
       }
          if (noheight == false ) 
       System.out.println("Player not found");
       System.out.println("**********************");
    } 
}

I hope you guys can help me to solve this problem.

CodePudding user response：

You have to use the findheight instead of n variable in your if (n == height[i]) condition:

try this it's work :

import java.util.Scanner;

public class Main{
    public static void main(String[]args){
        Scanner sc=new Scanner(System.in);

        System.out.println(" Welcome to VictoRoar Information System " );
        System.out.println( " ********************");

        System.out.print(" Enter n , number of player: ");
        int n = sc.nextInt();
        //declare,initialize array 
        String [] name = new String[n];
        double [] height = new double[n];
        sc.nextLine();

        //put input in the array 
        for (int i=0; i<n;i  )
        {
            System.out.print(" Enter player's name :" );
            name[i] = sc.nextLine();
            System.out.print(" Enter player's height (cm) :" );
            height[i] = Double.valueOf(sc.nextLine());
        }

        //search array
        System.out.print(" Write the player height that you want to know : ");
        double findheight=sc.nextDouble();
        boolean noheight = false;
        for(int i = 0; i<n; i  )
        { 
            if (findheight == height[i])
            {
                noheight = true;
                System.out.println("Player name "  name[i]   " with height "   height[i]  " present at index "  i);
            }
        }
        if (noheight == false ) 
            System.out.println("Player not found");
        System.out.println("**********************");
    } 
}

result:

Welcome to VictoRoar Information System 
********************
Enter n , number of player: 2
Enter player's name :Alex
Enter player's height (cm) :120
Enter player's name :David
Enter player's height (cm) :122
Write the player height that you want to know : 120
Player name Alex with height 120.0 present at index 0
