First you need to understand the mathematics behind it. Any number (that is a whole number, without a fraction part like for example 1.5) will give the reminder 0 when divided by one: n % 1 == 0 This condition will therefore always be true. If your case, once you are at n = 1, … Read more
How about a static import? // No promises this is compilable Java import static Landscape.createGrass; public class Wtv { public static void main(String[] argv) { int coord_x = 4; int coord_y = 7; createGrass(coord_x, coord_y); } } 2 solved Simplified Java Library? [closed]

== tests for reference equality. .equals tests for value equality. Threfore you should use: if (lista.getString(0).equals(“username”)) See How do I compare strings in Java? solved condition == between string and constant [duplicate]
So you have the following: if(condition1){ block1; } if(condition2){ block2; }else{ block3; } To disable/ignore the second if you can either use an else if statement: if(condition1){ block1; } else if(condition2){ block2; }else{ block3; } Or a return statement after block1 if(condition1){ block1; return; } if(condition2){ block2; }else{ block3; } 4 solved The if statement … Read more
You need a mechanism to input text from a source e.g. keyboard or command-line etc. Given below are some examples: From keyboard: import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print(“Enter a text: “); String s = scanner.nextLine(); for (int i = s.length() – 1; i … Read more
Your loop is equivalent to this: int i = 2; // Initializer while (i < 10) // Condition { System.out.println(i); i = i * i; // Update part } Note how it will never enter the body of the loop when i is 10 or greater – so it will never print 16. In other … Read more
As the user will use the virtual machine to run your program, he can always kill the JVM 🙂 2 solved How to create a process that cannot be killed?
You can run something like this: int numOfLines; //stores num of lines that will be inputted Scanner reader = new Scanner(System.in); //assuming you already imported before this numOfLines = reader.nextInt(); //captures 1st user inputted value int[] nums = new int[numOfLines]; //creates array object to captures all further values for (int i = 0;i<numOfLines-1;i++){ nums[i] = … Read more
