Q. How many of the following methods compile?

public class Test
{
public String convert(int value) {
return value.toString();
}
public String convert(Integer value) {
return value.toString();
}
public String convert(Object value) {
return value.toString();
}

public static void main(String... args) {
Test obj = new Test();
System.out.println(obj.convert(10));
}
}
