1.A class called circle is designed as shown in the following class diagram. It contains:

-Two private instance variables: radius (of type double) and color (of type String), with default value of 1.0 and "red", respectively.

-Two overloaded constructors;

-Two public methods: getRadius () and getArea ().

Write a test program called TestCircle which uses the Circle class and print the area of circle

2.Given an array of ints, return true if the array length is more than 1, and the first element and the last element are the same.

sameFirstLast ({1, 2, 3}) false s

sameFirstLast ({1, 2, 3, 1}) true

sameFirstLast ({1, 2, 1}) true

3.Set up an array to hold the following string values:

Reem (f)

Adnan (m)

Ali (m)

Sara (f)

Tareq (m)

Khaled (m)

Write a program to loop round and count how many are male and how many are female.
