Hi, I have some programs I'v been trying to create, as practice, but am having trouble. If anyone could point out some mistakes, I would be greatfull.
1. constructs rectangle, and prints its circumference:
import static java.lang.system.out;
class PerimeterTester {
Public static void main (Strings args[]){
int Width;
int Height;
int Perimeter;
Width = 4;
Height = 3;
Perimeter = 2*Width + 2*Height;
System.out.print("Perimeter: ");
System.out.println(Perimeter);
System.out.println("Expected: 90");
}
}
2. Creates 2 rectangles(r1,r2), and determines the rectangle(r3) caused by the intersection of the two rectangles. Prints them.
import static java.lang.system.out;
class PerimeterTester {
Public static void main (Strings args[]){
public r1(int x,int y,int width,int height)
public r2(int x1,int y1,int width1,int height1)
int x=;
int y=;
int width=;
int height=;
int x1=;
int y1=;
int width1=;
int height1=;
public r1 intersection(r2)
Rectangle r3 = r1.intersection(r2);
System.out.print("Rectangle 1: ");
System.out.println(public r1);
System.out.println("Rectangle 2:");
System.out.println(public r2);
System.out.println("Intersection:");
System.out.println(Rectangle r3);
}
}
3. Creates a random lottery number that consists of 6 values. (each value is a number between 1 and 49). Prints message, and the random number.
import static java.lang.system.out;
import java.util.Random;
class LotteryPrinter {
class Lottery {
public static void main (Strings args[]){
out.print(“Play this combination—it’ll make you rich!”);
int randomNumber1 = new Random(49)
out.println(randomNumber1)
int randomNumber2 = new Random(49)
out.println(randomNumber2)
int randomNumber3 = new Random(49)
out.println(randomNumber3)
int randomNumber4 = new Random(49)
out.println(randomNumber4)
int randomNumber5 = new Random(49)
out.println(randomNumber5)
int randomNumber6 = new Random(49)
out.println(randomNumber6)
}
}
I have been reading Java 2 for dummies, as well as some stuff on the internet, and figured the best way to learn would be to work on some easy programs hands on. But it seeme I cant even do that :o
Thanks for the help.
