level 7, lesson 12, name: the end. **stuck at "how to take input untill user types 'the end'"..? public static void main(String[] args) throws IOException { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); ArrayList s = new ArrayList();

public static void main(String[] args) { Thread.sleep(1000); for (int i = 30; i >= 0; i--) { System.out.println(i); Thread.sleep(1000); //write your code here } System.out.println("Boom!"); }

plz explain

BufferedReader b = new BufferedReader(new InputStreamReader(System.in)); ArrayList s = new ArrayList(); for(int a=0; a<10; a++) { s.add(b.readLine()); } ArrayList result = doubleValues(s); for( String x: result)

package com.codegym.task.task01.task0135; /* Two roads diverged in a yellow wood */ public class Solution { public static void main(String[] args) { System.out.println("Two roads diverged in a yellow wood,"); System.out.println("And sorry I could not travel both"); S

main method should display result of sqr method .need clarification.

package com.codegym.task.task04.task0404; /* Cat register */ public class Cat { private static int catCount = 0; public void addNewCat(int catCount) { this.catCount = catCount; } public static void main(String[] args) { Cat cat = new Cat();

public class Friend { String name; int age; char sex; public void initialize(String name){ this.name = name; } public void initialize(String name , int age){ this.name = name; this.age = age; } public void initialize(String name , int age, char sex){ this.name =

I was able to do my first program but I did not got the dark matter.

what seems to be the problem?

I DID FINISHED MY 3 PROGRAMS AND NOE IT IS PROPERLY RUNNING BUT I DID NOT GOT THE DARK MATTER HOW WOULD I CONTINUE.......!!!!!

package com.codegym.task.task02.task0217; /* Minimum of four numbers */ public class Solution { public static int min(int a, int b, int c, int d) { //write your code here int t; if(a

so far 'm abl to write code upto this. condition 3 needs solution in this, i read other soutions but unable to understand them. BufferedReader b = new BufferedReader(new InputStreamReader(System.in)); ArrayList l = new ArrayList(); for(int i=0; i<5; i++) {

package com.codegym.task.task05.task0532; import java.io.*; /* Task about algorithms */ public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int maximum = 5; /

??

i entered value in (system.in) both in vertical manner and horizontal manner and then click the run button, error and if i click without entering value, even then the same error.. public static void main(String[] args) throws Exception { int[] array = initializeArray(); int max = m

package com.codegym.task.task01.task0127; /* Square of a number */ public class Solution { public static void main(String[] args) { int a = sqr(5); System.out.println("the square of 5"+ a * a); } public static int sqr(int a) { return a * a; } }

What is more convenient to use scanner class or bufferreader... am confused

how to solve ..the system says that i have a typo error i think

System.out.println("Your salary is: "+a+" dollars per month");

GIVE ME A SOLUTION

Save a reference to the previously created Woman object in man.wife. Save a reference to the previously created Man object in a woman. husband (Hint: woman.husband = man). I didn't understand this.

How to solve this?

how to overcome this problem?

"- create a copy of another rectangle passed as an argument" - This is what I don't understand here so please kindly help me This statement applies to 4th initialize method only. Thanks.

The code apparently satisfies all conditions except "3. After entering -1, the program must correctly terminate." Though with "Run (without verification)", I get the required results for all the combinations listed..

what is wrong in this? help please
