Question

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner scan= new Scanner(System.in);
System.out.println("CHOOSE AN OPERATOR * + / -");
String o= scan.nextLine();

System.out.println("Type Any Number");
int n1= scan.nextInt();
System.out.println("Type The Second Number:" );

int n2= scan.nextInt();

if (o=="+") {

System.out.println(n1+n2);

}

}

Answer 1

Use
(o.equals("+")) instead of (o=="+")

edit: you have a brace } missing at end. add it.
