Create a text file in Java, then Write complete Java code to Write the following text to Text file “Java is an object-oriented programming language know" Finally, write Java code to read the text from the text file and display it on the jTextFields.
Exercise 1: Write a Java application that reads scores of students from a user and display the course grades and Student Information. There are two types of students: undergraduates and postgraduates. Every student will have an ID, a name, and college. The undergraduate students are assessed by three components: test one (40%), test two (40%) and quizzes (20%). The postgraduate students are also assessed by three components: test one (30%), test two (30%) and a project (40%). You should develop your application according to the following specifications: Create Student class as superclass and undergraduates and postgraduates as subclasses. Every student has an id, a name, and a college. • Both undergraduates and postgraduates will have two exams (with different weights as explained above). An undergraduate is a student who has also quizzes. Similarly, a postgraduate is a student who has a project. All assessment components are out of 100. The final score of an undergraduate or a…

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.…

Integer userValue is read from input. Assume userValue is greater than 1000 and less than 99999. Assign tensDigit with userValue's tens place value. Ex: If the input is 15876, then the output is: The value in the tens place is: 7 2 3 public class ValueFinder { 4 5 6 7 8 9 10 11 12 13 GHE 14 15 16} public static void main(String[] args) { new Scanner(System.in); } Scanner scnr int userValue; int tensDigit; int tempVal; userValue = scnr.nextInt(); Your code goes here */ 11 System.out.println("The value in the tens place is: + tensDigit);

Look at this program: int main(){ int x = 4; displayMessage(); return 0;}void displayMessage(){ for(int x = 1; x <= 100; x++) cout << "I love computer science" << endl;} What will the output be? Answers: Nothing. It won't compile because you can't define the variable x inside a loop heading. Nothing. It won't compile because the displayMessage function is being called before it has been defined "I love computer science" 100 times "I love computer science" Nothing. It won't compile because you can't call a void metho

In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
