I keep getting errors with my Boolean statement to affirm whether it is a triangle or not, please help with the formatting.

Help, please

plz tell my error

?

I have tried everything. Finally I created 3 lists .Or do I have to create another constructor for storing objects.

When i run program works correctly but.........can't verify.............. Plz help me out this ........

What does it mean "You must initialize an existing string field with a new ArrayList."?

?

?

I can make this code "work" but not verify. The verification says to make sure it calculates everything properly. I have tried many different versions of this task and I am not getting what I am missing. Any help would be appreciated. Thank You.

Problem Here? Why won't this validate. I get the right answer each time.

public class Solution { public static void main(String[] args) { try{FileInputStream stream = new FileInputStream(args[0]); int n1 = 0; int n2 = 0; int a; while (stream.available() > 0) { a =stream.read(); n1 += a; Strin

I don't know how to set my condition in line 25, because it shows "java.lang.IndexOutOfBoundsException " Can anyone give me some advice? Thanks a lot~

public static void main(String[] args) throws Exception { //write your code here int[] big = new int[20]; BufferedReader r = new BufferedReader(new InputStreamReader(System.in)); String s; for (int i = 0; i<20 ; i++){ s = r.readLine();

It says it won't compile on the server but it runs fine on my computer? public class StringHelper { public static String multiply(String s) { return s.repeat(5); } public static String multiply(String s, int count) { return s.repeat(count); } public static voi

not getting variable plz helppp

Whats wrong

BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); String n1 = reader.readLine(); char ch = n1.charAt(0); int n = Character.getNumericValue(ch); if (n % 2 == 0){ even++; } else if (n % 2 ==1){ odd++

how do you display nothing

package com.codegym.task.task01.task0108; /* 2 + 3 = 5 */ public class Solution { public static void main(String[] args) { int a = 3, b = 2; /* System.out.print("two");*/ System.out.print(b); System.out.print(" plus ");/* System.out.print(" minus ");*

public static void main(String[] args) { //write your code here System.out.println(convertEurToUsd(45)); System.out.println(convertEurToUsd(34)); } public static double convertEurToUsd(int eur, double exchangeRate) { //write your code h

task08.task0814 - Greater than 10? You're not a good fit for us When I run it has removed elements > 10. But not according to codegym vaerify?

I'm just throwing solutions at the wall at this point to see what sticks. While loops do not satisfy any of my missing requirements. My real problem is with the 1000 repetitions, all forms of my solution fail to pass Thread.sleep(1) 1000x requirement, though I know they are repeating 1000 times (0-9

package com.codegym.task.task01.task0134; /* Fill a pool with water */ public class Solution { public static void main(String[] args) { System.out.println(getVolume(25, 5, 2)); } public static long getVolume(int a, int b, int c) { //write your code here long

I have used BufferedReader and I have written a code, whose output doesn`t match the code. I need to somehow assign a value to name and y, even though it´s supposed to be read from the keyboard. Can anyone help?

task08.task0802 - HashMap of 10 pairs Initialization failing verify. why?

task08.task0801 - HashSet of plants Verify failing declare/initialize HashSet why?

i have written it correctly but its showing

Help needed on code and logic

Upon verification it says that "The program should display the minimum of two integers." It couldn't be much simpler package com.codegym.task.task04.task0418; /* Minimum of two numbers */ import java.io.*; public class Solution { public static void main(String[] args) throws Exception {
