Design and implement a class named RightangleTriangle that extends a GeometricObject class. The class contains:  

• Two double data fields named baze and hite with default values 3.0 and 5.0 to denote base and height of the right-angle triangle. 
• A no-arg constructor that creates a default triangle. 
• A constructor that creates a triangle with the specified base and height. 
• The accessor methods (getter and setter) for all the data fields.  
• A method named getArea() that returns the area of this triangle. 
• A method named printData() to print all data field values in console. 

The superclass à GeometricObject class should have following data fields: private String color = "white"; private java.util.Date dateCreated; 

• Implement all types of constructors to initialize and set these data fields. Use super keyword to set these values in your triangle class.  
• Implement another class mainClass where you create an object t1 of the RightangleTriangle class and print its area and the value of all its data fields. 

Write a program to create a class Circles with the following information:

radius in integer.

Add two constructors, (a) default constructor, and (b) constructor to pass on radius of a Circle.

Add a method printData( ) to print the radius of the Circle in console.

Add methods printArea( ) and printPerimeter( ) to compute and print the area and perimeter of Circle in console.

Create two objects of this class, c1 and c2. Show the output of both the constructors and all methods of these two objects

Write a program to create an array in order to store 30 numbers then display the highest number and second highest number present in it using bubble sorting.

Maze Game

General Rules:

1. Use the collision detection method for the wall(obstacle).

2. Once collided with any part of the obstacles, the object will go back to its starting position and lose 1 life(3 lives

in total). It must indicate how many lives are left during the game.

3. Once life falls below zero(0), the last collision will automatically stop the game and display “Game Over” in any

part of the program.

4. After the object reaches the finish line, the text “Congratulations” must appear in any part of the program

The movement of the object depends on the keyboard event triggered by the user. It must be W, A, S, D or

Arrow UP, DOWN, LEFT, RIGHT. (Just like pacman game movement)

you have been an integer array A of size N.you need to pfint the number with the value closest to zero.if there are multiple elements print the number with greater value.

Write a program to display sum of the following series:

1-3+5-7+9.....n terms

Using following method prototype:

int  series(int n)

If Input is given the above series i.e. 1-3+5-7+9

then output will be 5...

Write a program to create two single dimension arrays to store names and marks of 25 students. Then display the name of the students who secured more than 90 as per their marks in descending order and also display how many such students found.

Hint: Use Linear search and Bubble sorting.

Program the following in Java language.

Implement the following equation

3x4sin(180x) + 4x3 cos(90x) + x2sin(tan(45)) + 7x + 9cos(90x2 )

where x may be user defined value.

The statements in the following program are in incorrect order. Rearrange the statements so that it prompts the user to input the shape type (rectangle, circle, or cylinder), and the appropriate dimension of the shape. The program then outputs the following information about the shape: For a rectangle, it outputs the area and perimeter; for a circle, it outputs the area and circumference; and for a cylinder, it outputs the volume and surface area. After rearranging the statements, your program should be properly indented. 

Use Spring MVC + Hibernate to do the following

Main page to display two Links

Save student exam data

Display all the students data

Student Exam Data Form would contain the following

Basic Student Details and Address with Validations

Details of Marks for Five Subjects (All marks subjects should be >= 0)

Save all the marks to an arraylist

The display Page would list all the students in decreasing order of percentage

Web Application

Main

- Link to upload student marks

- Display all the student marks

Form

Roll Number (*) -> EDYXXXX (Roll Number should start with EDY and XXXX means digits)

First Name (*)

Last Name

All the marks have to be greater than or equal 0

- If validation fails please display error.

Submit the form.

Store it in any Collection (DB).
