Java overload confusion

Question

java is not able to call any overload method as shown below :-

class LspTest{

    public void add(int a, float b){
    System.out.println(\"First add\");
}         


        

Answer 1

When you initialise with literal values, in this case, compiler won't be able to infer the exact type. Therefore, it does not know which overload to call and returns the error that the reference to add is ambiguous. You can fix this by casting the arguments to the appropriate type, or even better, creating typed local variables initialised with 1 and passing the variables as parameters, like so:

int a = 1;
float b = 1;
LspTest test = new LspTest();
test.add(a,b);
