Thread: What's wrong with my code?? (it said cannot resolve symbol)

Here is my code:

import java.util.*;

public class Coin {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.println("How many times you want to flip?");

int time=input.nextInt();

int array[]=new int[time];

int showtime[]=new int[10];

int head=0,tail=0,most=0;

String output="";

System.out.println("Generate: ");

for (int x=0;x<time;x++) {

int a=(int) (Math.random()*10+1);

System.out.print(a+" , ");

array[x]=a;

showtime[a-1]++;

if (a%2==0) head++;

else tail++;

}

System.out.println();

for (int x=0;x<10;x++) {

System.out.println("No. \""+(x+1)+"\" showed "+showtime[x]+" time(s)");

if (showtime[x]>showtime[most]) {

most=x;

output="The number(s) that showed up the most: "+(x+1);

}
else if (showtime[x]==showtime[most])

output=output+" , "+(x+1);

}

System.out.println(output);

if (head>tail) System.out.println("Heads came up the most");

else if (head==tail) System.out.println("Heads=Tails");

else System.out.println("Tails came up the most");

}

}

What's wrong with my code??

I just tested out the code using eclipse, and everything works fine for me! Check to see if there are any comments using strange symbols. Other than that, the code you posted is solid and works fine!

Here is the error message.

Why can't it find the Scanner class?

Try adding

import java.util.Scanner;

He has

 import java.util.*;

though, and that should cover it.

It compiles for me as is.

It is still not working. It said that cannot resolve the scanner class....

When I add "import java.util.Scanner;" it creates another error.... saying error on the Scanner class.....

My error:

flip.java:7: cannot resolve symbol
symbol  : class Scanner
location: class flip
                Scanner input=new Scanner(System.in);

mine is 1.4.2. So what can I do??

I think some syntax problem can you send me complete coding which are using in your program.

so, what can I do to replace the Scanner class in my 1.4.2 version?? How do I do it??

Is there any examples?? Like how do I start? I forgot how to do a wrapper class
