Program

public class Main
{
    public static void main(String args[])
    {
        char ch='#';
        if(!(ch>='0' && ch<='9' || ch>='a' && ch<='z' || ch>='A' && ch<='Z'))
        {
            System.out.println("Symbol");
        }
        else
        {
            System.out.println("Not a Symbol");
        }
    }
}

Using CommandLine Arguments

public class Main
{
    public static void main(String args[])
    {
        char ch;
        ch=args[0].charAt(0);
        if(!(ch>='0' && ch<='9' || ch>='a' && ch<='z' || ch>='A' && ch<='Z'))
        {
            System.out.println("Symbol");
        }
        else
        {
            System.out.println("Not a Symbol");
        }
    }
}

Using Scanner Class

import java.util.*;
public class Main
{
    public static void main(String args[])
    {
        char ch;
        Scanner s=new Scanner(System.in);
        System.out.println("Enter character");
        ch=s.next().charAt(0);
        if(!(ch>='0' && ch<='9' || ch>='a' && ch<='z' || ch>='A' && ch<='Z'))
        {
            System.out.println("Symbol");
        }
        else
        {
            System.out.println("Not a Symbol");
        }
    }
}
