hello,
please tell me why i'm getting this error

D:\javafiles\Exam2.java:8: cannot find symbol
symbol : method parseInt(char)
location: class java.lang.Integer
int cell=Integer.parseInt(shap);
^
D:\javafiles\Exam2.java:17: plot(char,int) in Exam2 cannot be applied to (java.lang.String,int)

Process completed.

Code java:

---

 
import  java.lang.*;
import java.util.*;
 
public class Exam2
{
	public static void plot(char shap, int iter)
	{
		int cell=Integer.parseInt(shap);
		for(int i=0; i<iter;i++)
			System.out.print(cell+" ");
	}
 
	public static void main(String [] args)
	{
		for(int i=0; i<4;i++)
		{
			Exam2.plot("1",4);
			Exam2.plot("0",4);
		}
	}
}

Code :

---

import  java.lang.*;
import java.util.*;
 
public class Exam2
{
    public static void plot(char shap, int iter)
    {
        int cell=Character.digit(shap,10);
        for(int i=0; i<iter;i++)
            System.out.print(cell+" ");
    }
 
    public static void main(String [] args)
    {
        for(int i=0; i<4;i++)
        {
            Exam2.plot('1',4);
            Exam2.plot('0',4);
        }
    }
}

you defined "shap" as character type, but you pass in a String. Use single quote for character.
Integer.parseInt takes in a String (check the API documentation ) , if you want to use a character, you can use Character class digit() method to convert a character to an integer.

OR

In case if you don't want to get lost in the world of Java API documentation, them simply change the signature of your plot method. Take String instead of a char.

Change this,

Code java:

---

public static void plot(char shap, int iter)

---

to this

Code java:

---

public static void plot(String shap, int iter)

---

This will resolve all your errors.

And one more thing, why have you imported the java.lang package?

Code java:

---

import java.lang.*;

---

The lang package comes inbuilt for every java class. We don't need to import it explicitly. There is nothing wrong with it, but why to add lines of code for the things which are already available? /:)

Hope that helps!

Thank you very much Mr.JavaHater and Mr.Goldest for your help.
it works know
