Question

Java Question. Please provide a correct solution with steps. Will provide a thumbs up for correct solution. Answer as soon as possible.

What is type argument inference? Why does a generic method look like an indefinite overloaded method?

Answer 1

Type argument inference is a process performed by the compiler to determine the actual type argument for a type parameter when invoking in a generic method.

Example of generic method:
-----------------------------
static <T> T add(T a1, T a2) {
    return a1+a2;
}

Example of overloaded methods according to above generic method:
------------------------------------------------------------------
static int add(int a1, int a2){
    return a1+a2;
}

static float add(float a1, float a2){
    return a1+a2;
}

.....
.....

static String add(String a1, String a2){
    return a1+a2;
}


So, From the above we can say that if we write all indefinite overloaded methods then that will equals to the above genetic method.
