What is the problem with my if statement? (java) [closed]

Spent so long trying to figure out what's wrong, I am new to Java and basically a beginner programmer, making the answer simple for me to understand will be greatly helpful. Thank you.

import java.util.Scanner;

public class CheckingTheAge {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        System.out.println("How old are you?");
        int age = Integer.valueOf(scanner.nextLine());
        
        if ( age => 0 && age =< 120) {
            System.out.println("OK");   
        } else {
            System.out.println("Impossible!")
        }
    }
}
