IN JAVA Create a function that takes a string and returns the number of alphanumeric characters that occur more than once. Examples duplicateCount ("abcde") → 0 duplicateCount ("aabbcde") → 2 duplicateCount ("Indivisibilities") → 2 duplicateCount ("Aa") → 0 // Case sensitive

Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. /** * Returns a String representation of this vector. The String should be in the format "[1, 2, 3]" * * @return a String representation of this vector * @apiNote **DO NOT** use the built-in (@code Arrays.toString()} method. */…
8) Now use the Rectangle class to complete the following tasks: - Create another object of the Rectangle class named box2 with a width of 100 and height of 50. Note that we are not specifying the x and y position for this Rectangle object. Hint: look at the different constructors) Display the properties of box2 (same as step 7 above). - Call the proper method to move box1 to a new location with x of 20, and y of 20. Call the proper method to change box2's dimension to have a width of 50 and a height of 30. Display the properties of box1 and box2. - Call the proper method to find the smallest intersection of box1 and box2 and store it in reference variable box3. - Calculate and display the area of box3. Hint: call proper methods to get the values of width and height of box3 before calculating the area. Display the properties of box3. 9) Sample output of the program is as follow: Output - 1213 Module2 (run) x run: box1: java.awt. Rectangle [x=10, y=10,width=40,height=30] box2: java.awt.…

Here is a statement: class temporary { public: void set(string, double, double); void print(); double manipulate(); void get(string&, double&, double&); void setDescription(string); void setFirst(double); void setSecond(double); string getDescription() const; double getFirst()const; double getSecond()const; temporary(string = "", double = 0.0, double = 0.0); private: string description; double first; double second; }; How can I write a definition of the member function manipulate that returns a decimal number as follows: If the value of description is "rectangle", it returns first * second; if the value of description is "circle", it returns the area of the circle with radius first; if the value of description is "sphere", it returns the volume of the sphere with radius first; if the value of description is "cylinder", it returns the volume of the cylinder with radius first and height second; otherwise, it returns the value -1.
