JAVA Objects

so you cannot declare two methods with the same signature even if they have a different return type.

Why so the return type is different suppose you want same signature for another method in the code. what you will do ?

different return type but same signature

like that if you create a signature it will be used only once in the whole program

What do you mean by "signature"...? You can do this

public void hotDogs() {

}

public void hotDogs(String toppings) {

}

or even

public boolean hotDog(String toppings, int amount) {

}

but I don't think you can do

public void hotDogs() {

}

public boolean hotDogs() {

}

Does this help?

The Java language does not allow two methods with same name to have identical parameters and different return types.

It will result in a compile-time error.
