So in the example below they want to give a example that multiple methods can have the same name with different parameters:
I have a few questions:
I thought variables had unique names, how does it knows we talk about the same x + y. I assume the variables are only defined within the method then, right? And not within the whole public class MyClass
Second:
Why does the double return the value 10.5599999999999 instead of 10.56
If I edit 6.26 to 6.27 it will return 10.57
public class MyClass {
static int plusMethodInt(int x, int y) {
return x + y;
}
static double plusMethodDouble(double x, double y) {
return x + y;
}
public static void main(String[] args) {
int myNum1 = plusMethodInt(8, 5);
double myNum2 = plusMethodDouble(4.3, 6.26);
System.out.println("int: " + myNum1);
System.out.println("double: " + myNum2);
}
}
Result:
int: 13
double: 10.559999999999999
Third
Why call the method the same if your using different types of variables. Will those variables called x be usable if you call on x and there is a value int 2 and float 4.21
Example in tutorial.
int myMethod(int x)
float myMethod(float x)
double myMethod(double x, double y)
Thank you
