why am i getting an error in the pass by reference example obj1.add200really is underlined

public class testTest {
    
    private int number;

    testTest(){
        number = 1;
    }
    
    public static void main(String[] args) {
        testTest obj1 = new testTest();
        System.out.println("the number is " + obj1.number);
        System.out.println("the number 1 plus 200 is " + obj1.add200(obj1.number));
        System.out.println("while the number is still " + obj1.number);
        System.out.println("\n");
        System.out.println("the number is " + obj1.number);
        System.out.println("the number 1 plus 200 is " + obj1.add200really(obj1.number));
        System.out.println("while the number is still " + obj1.number);
    }


int add200(int somenumber){
    somenumber = somenumber + 200;
    return somenumber;
}
int add200really(testTest myobj){
    myobj.number = 999;
    return myobj.number;
