Integer numLengths is read from input. Then, numLengths integers are read from input and inserted at the end of lengthList. If an element is at an even index in lengthList, negate the element. Ex: If the input is: 2 49 33 then the output is: -49 33 Note: Index i is even if i % 2 == 0.

In Java Use a given class API to create objects and call static and non-static methods of that class.

Java

1. We want to create an interface to represent pets. What are some of the methods that will be in our interface? 2. Take one of the methods you listed above. Defend how it fits the criteria necessary for it to be used in an interface and not in an inherited class. 3. Write out what this interface would look like in Java.

QUESTION 3 For an array of objects The array can contain objects of different types at run time but must be defined as the same object type in Java code. The array can contain objects of different types at run time and can be defined as different object types in Java code. The array can't contain objects of different types at run time and must be defined as the same object type in Java code. The array can't contain objects of different types at run time but can be defined as different object types in Java code.

Please write in Java and use Math.PI for pi. I wrote the print statements to use in the program. The screenshot explains the question.

Create a one dimension array in java for class number (i.e. COMSCI101), class description (i.e. introduction to Java), class units (i.e. 3 grade points), grade (i.e. A, A-, B+, B, B-, C+, C, C-, D, F), and grade points (i.e. 12.0 for an A). I also have to ask the user to input the class number, description, units, grade, and grade points obtained. Then I have to convert the grade to a number (i.e. A = 4.0 and so on).

do this with java

Assume class ArrayStack has been deńned using the implementation in your textbook and that myStack has been initialized so it is empty. Type the EXACT output of the following code segment. You may assume that the code compiles and executes without errors. ArrayStack my5tack; int i = 1; int j = 2; int k = 3; int n = 4; myStack.push (); myStack.push (k); i = my5tack.peek (0: myStack.pop (); myStack.push (n); k = myStack.peek (); myStack.pop (); my5tack.push (n); my5tack.push (1); myStack.push (k); while (Imy5tack.isEmpty () { i = my5tack.peek (); my5tack.pop (); cout << i<< ""; cout << endl;

Please help me make a game with Java. The game should have only a class and needs to include at least 3 of the following AP topics: String Array, ArrayList, 2D Array Interfaces and/or Abstract classes Polymorphism Inheritance Searching Algorithms Sorting Algorithms Recursion   You also need to include a new topic that is different than the above. Once you finish creating the game, please show me the new topic that you included and let me know what are the other 3 topics that you chose from the list above and what was challenging.
