Write A Method Which Initializes A 2D Target Array

Apr 11, 2014

So here is a method i wrote for the first part for initializing an array:The question was, "write a method which initializes a 2D target array (assuming all other classes have been imported and given), and all targets should be stationary."and this was my method i wrote:

public void initializeTargetArray(Target[][] targets) {
int row = targets.length();
int col = targets[0].length;

for(int i = 0; i < row; i++)
for (int j = 0; j < col; j++)
targets[i][j] = new Target(Target.STATIONARY, false);
}

Now my question how do I initialize an array similar to the method above for a different question?

Quote
Part b
Write a method which initializes an array (You can assume that the 2D array itself (but not the Target
objects inside) is already initialized), where the game level stage is now set:
Game level 1 - all targets are stationary,
Game level 2 - For even numbered rows, targets at even numbered columns are stationary, targets at odd
numbered columns are movable. For odd numbered rows, targets at odd numbered columns are
stationary, targets at even numbered columns are movable.
Game Level 3 - All targets are movable.

public void initializeTargetArray(Target[][] targets, int gameLevel) {
//*** Finish this method. ***//

Write A Method Called AddToOverThirty Which Takes Array Nums3 As A Parameter

Apr 22, 2014

i have to "Write a method called addToOverThirty which takes the array nums3 as a parameter. It adds 1 to all numbers that have a value greater than 30 in the array.

Add a call to the addToOverThirty method, then display a message telling what the output is followed by the results For example:The nums3 array after adding 1 to all numbers greater than 30 is10 6 15 and so on (check with the values you assigned to nums3)"its pointless because we were told not to make the array have a number over 30.

import java.lang.*;
import java.util.*;
public class LastProject
public static void main(String[] args) {
int nums1[] = new int[15];
int nums2[] = new int[15];
int nums3[] = {5,2,15,8,26,22,1,29,4,23,30,11,19,6,24};

Constructs And Initializes A Point With Same Location As Specified Point Object

Jun 5, 2014

I was reading the oracle java tutorial under: URL....Here's the code for the Point class:

public class Point {
public int x = 0;
public int y = 0;
//constructor
public Point(int a, int b) {
x = a;
y = b;
}
}

and in the Rectangle class you have the following constructor:

public Rectangle(Point p, int w, int h) {
origin = p;
width = w;
height = h;

If we create a new Point object like this:

Point originOne = new Point(23, 94);

and then a new Rectangle object like this:

Rectangle rectOne = new Rectangle(originOne, 100, 200);

Will that set originOne to point to the object Point at (23, 94). just want to make that this is the meaning of this statement: Point(Point p)Constructs and initializes a point with the same location as the specified Point object.

How To Write Inorder-method For Trees

Mar 29, 2015

I have a question related to trees in Java. The following code is given:

public class BinarySearchTree {
private Node root;
public BinarySearchTree() {
this.root = null;

public BinarySearchTree(Node root) {

The inorder-method is the one that really imports. I have to go through a tree using the Inorder-method. I do understand how this works, however I don't understand how the code fits to the inorder process. I understand the code up to the point where it reaches the most left "root", but then I do not know how to go further. How do I reach the root above then?

How To Write Conversion Method From Roman Numerals To Arabic

Nov 8, 2014

I am a student taking a Java programming class. My assignment is to write a program that converts a roman numeral input as entered by a user and converting it to it's integer value (arabic number). These are the methods that I must have in it:

1. Write a method that takes input from the user and passes it to a conversion method.
2. Write a method that yields the numeric value of each of the letters (conversion method).
3. Write a method that outputs the number the user entered and the converted number.
4. Write a main method to test the 3 methods.

I have written the first method, at least I think. Here is what I did there:

public static String romanInput(String number) {
Scanner numberInput = new Scanner (System.in);
System.out.print("Enter a roman numeral: ");
String userInput = numberInput.next();
return userInput;
}

I returned the userInput and I think that is passing it to the conversion method? Now I am working on this conversion method and to be honest I don't know where to begin. I am told how to convert a string in my assignment by the professor. I am told:

- Look at the first two characters. If the first has a larger value than the second, then simply convert the first.
- Call the conversion method again for the substring starting with the second character.
-Add both values. If the first one has a smaller value than the second, compute the difference and add to it the conversion of the tail.

I am also told to use a single-dimensional array. But, I don't know what I am to use a single dimensional array for? So this is what I wrote so far for this method:

public static int numberConversion(int number) {

int romanConv = 0;
char[] romanNum = {'I', 'V', 'X', 'L', 'C', 'D', 'M'};
char[] arabicNum = {1, 5, 10, 50, 100, 500, 1000};
romanNum = arabicNum;
}

I have written a character array for the roman numerals, and then one for arabic numerals, then I set them equal to each other. I also declared an integer variable set to 0 because I think that is what I will be returning at the end of the method. Now I don't know where to start for the conversion algorithm here. I know this is what I have to do, but I don't know how to do it:

1. Add the numbers together if they are in decreasing value or are equal in value. For example: VI is read as 5 + 1 = 6 XVI is read as 10 + 5 + 1 = 16 XXXVIII is 10 + 10 + 10 + 5 + 1 + 1 + 1 = 38
2. Use subtraction if a number is less than the number that follows it. For example, I is less than V, so when I is in front of V, you subtract its value.
3. For example: IV is 5 1 = 4 IX is 10 1 = 9 XL is 50 10 = 40 MCM is 1,000 + (1,000 - 100) = 1,900

I can't use hashtables or enums because I haven't learned about that yet. I have a feeling I need to use a for loop. I know I haven't done any of the actual programming work but I don't know how to begin writing this conversion method.

Write an instance method, contains, that has one explicit parameter of type Rectangle. The method should return true if every point of the rectangle determined by the explicit parameter is on or within the rectangle determined by the implicit parameter. It should return false otherwise.

This is what i did so far?

public boolean contains(Rectangle other) {
Rectangle intersect = Rectangle.intersection(this, other);
if ((intersect.left == this.left) && (intersect.bottom == this.bottom) && (intersect.width == this.width)

Write A Program That Will Call A Method To Calculate Function

Dec 3, 2014

I have understood my programming class up to this point and now I have been given a lab that I can't figure out for the life of me. Here what I have to do: Write a program that will call a method (called f) to calculate the following function" f(x)=(x^2)-16...this is what the output should be:

x f(x)
1 -15
2 -12
3 -7
4 0
5 9
6 20
7 33
8 48
9 65
10 84

I guess it also has to print this output in a table even though my professor never mentioned it. Usually

public class Lab12 {
public static int f(int x)
{
return x*x-16;

Write A Static Method That Simulates Flip Of Weighted Coin

Apr 22, 2015

I am supposed to write a static method that simulates a flip of a weighted coin by returning either heads or tails each time it is called. The coin is twice as likely to turn up heads as tails. My idea was to of course use a random class

Random flip = new random

and somehow initialize it so 3 numbers are called and create if statements so that when 0 and 1 are called heads returns and when 3 is called tails is.How do I put all this together?

Write A Program To Create Integer Array Of Size 20

Aug 2, 2014

Write a program to create an integer array of size 20. Then, the program should generate and insert random integers between 1 and 5, inclusive into the array. Next, the program should print the array as output.

A tremor is defined as a point of movement to and fro. To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.

Then, the final array should be printed as output. There is no user input for this program.Your program must include, at least, the following methods:

-insertNumbers, which will take as input one integer array and store the random numbers in it.
-createTremor, which will generate the random number as the location and return it.

A sample run of the program is shown below:

Sample output #1:
Array:1 2 2 3 1 5 4 2 3 4 4 2 1 1 3 2 1 4 3 2 1
Random position: 5
Final Array:1 2 0 0 0 5 0 0 0 4 4 2 1 1 3 2 1 4 3 2 1
