So I have been messing around with this trying to make a simple calculator while also using methods. For some reason when checking if the string "func" is equal to "*" it skips and instead returns "Unknown" it also happens when imputing the other functions

package test;
import java.util.Scanner;

public class test {

    public static float num1;
    public static String func;
    public static float num2;
    public static float awnser;

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

        System.out.println("Simple Calculator");
            num1 = input.nextFloat();
                func = input.next();
                System.out.println(func); //Confirms func=="*"
                    num2 = input.nextFloat();
                        times();}
public static void times() {
     if(func=="*"){awnser=num1*num2;}
     else if(func=="/"){awnser=num1/num2;System.out.println("The awnser is: "+awnser);}
     else if(func=="+"){awnser=num1+num2;System.out.println("The awnser is: "+awnser);}
     else if(func=="-"){awnser=num1-num2;System.out.println("The awnser is: "+awnser);}
        else {System.out.println("Unknown");}}}

OUTPUT:

1. Simple Calculator


2. 5


3. *


4. *


5. 5


6. Unknown
