How do you make Java look for specific characters in user input

Question

I was working on a Java calculator and happened to run into these errors as I was testing the input (I imported Java Scanner);

./Playground/Program.java:24: error: incompatible types: String cannot be converted to Scanner
if (way = "+") {
^
./Playground/Program.java:24: error: incompatible types: Scanner cannot be converted to boolean
if (way = "+") {
^
./Playground/Program.java:25: error: bad operand types for binary operator '+'
System.out.println(num1 + num2);
^
first type: Scanner
second type: Scanner
3 errors

Answer 1

If you want to work with chars:

char input = scan.next().charAt(0);

if(input == '+'){

...

}

" " -> String
' ' -> char

Answer 2

import java.util.Scanner;

Scanner scan = new Scanner(System.in);

String input = scan.next();

if(input.equals("+"){

...

}

For comparison:
primitives like int or char use ==
objects like String use .equals()
