(method overloading)

given the following methods, write down the printed output of the method calls:

public static void dosomething(string x) { system. out. println("a");
}
public static void dosomething(int x) { system. out. println("b");
}
public static void dosomething(double x) { system. out. println("c");
}
public static void dosomething(string x, int y) { system. out. println("d");
}
public static void dosomething(int x, string y) { system. out. println("e");
}
public static void dosomething(double x, int y) { system. out. println("f");
} method calls
1. dosomething(5);
2. dosomething (5.2, 9);
3. dosomething(3, "hello");
4. dosomething("able", 8);
5. dosomething ("alfred");
6. dosomething (3.6);
7. dosomething("world");

1. doSomething(5);  

   B

2. doSomething (5.2, 9);  

    F

3. doSomething(3, "Hello");  

    E

4. doSomething("Able", 8);  

    D

5. doSomething ("Alfred");  

    A

6. doSomething (3.6);  

   C

7. doSomething("World");

   A

Explanation:

Method overloading is an ability available in some programming languages such as Java to enable two or more methods share the same name but with different argument list.

For example, a method with a single string argument doSomething(String x). The method can be overloaded by having a different argument list as follows:

When calling the method with a specified argument list such as doSomething("Able", 8), only the matched version (e.g. doSomething(String x int y)) will be invoked and print out D.

a) click on any cells in the range of data

b) click the data

c) click sort& filter group, click sort

d) select the column to sort by and then select a sort order

e) select the next column to sort by and select the sort order

f) click ok
