Thread: My 'if statements' are skipped after user input

The program shuts down right after I receive input for a String and an int variable, and I'm really confused as to why it's doing this. Any help at all would be greatly appreciated.

 
import java.util.Scanner;
 
class Tempurature{
    public static void main(String args[])
	 {
Scanner in = new Scanner(System.in);
 
        int tempNum;
        String tempScale;
 
        System.out.print("Type F for Fahrenheit or C for Celsius: ");
	tempScale = in.nextLine();
        System.out.print("Enter the tempurature: ");
        tempNum = in.nextInt();
 
if (tempScale == "C" && tempNum >= 100)
 
        System.out.println("Your water is boiling."); 
 
if  (tempScale == "F" && tempNum >= 212)
 
        System.out.println("Your water is boiling.");
 
if  (tempScale == "F" && tempNum >= 212)
        System.out.println("Your water is liquid.");
 
 
else if (tempScale == "C"  && tempNum <= 100)
        System.out.println("Your water is liquid.");
 
    }
}

Well now I am getting errors around my "&&" in this line:

if (tempScale = "C" && tempNum >= 100)
 
        System.out.println("Your water is boiling.");

Do I need to convert "C" to a number? If so then could I get some help on that as well?

Sorry about that. The error I get is "not a statement" on the && part. I'm not particularly sure what I need to do to fix it.

 
if ((tempScale) equals("C") && (tempNum >= 100));
