Whoops, my bad, I put one of my statement in the wrong order in my code.

Java
I having problems in the fruit list aryan-firouzian.

Sample test
public class SolutionTest {
@Test
public void basicTest() {
assertEquals("apple", Kata.subtractSum(10));
}
}

Fruit list from instructions
1-kiwi
2-pear
3-kiwi
4-banana
5-melon
6-banana
7-melon
8-pineapple
9-apple
10-pineapple
11-cucumber
...
Apple is at 9. Yet test is expecting at 10.

I think your fruit list in instruction is incorrect because I am getting mixed results(1 correct 1 wrong for random numbers) whenever clicking 'Attempt'.

Palindromization - Java 1.8.0_91(Java 8)
I have problem with the exercise. When I run the sample test without modifying the code I get following error message.
STDERR:
/workspace/java/src/KataTests.java:28: error: class, interface, or enum expected
}
^
1 error

I noticed that there is addition closing curly brace (}) with no opening brace.

Default code

public class Kata {
public static String palindromization(String elements, int n) {
return elements;
}
}

Sample Test

import org.junit.Test;
import static org.junit.Assert.assertEquals;
import org.junit.runners.JUnit4;
public class KataTests {
@Test
public void Error_Cases() {

    assertEquals(Kata.palindromization("", 2), "Error!");
    assertEquals(Kata.palindromization("123", 1), "Error!");

}

@Test
public void Examples() {
    
    assertEquals(Kata.palindromization("123", 2), "11");
    assertEquals(Kata.palindromization("123", 3), "121");
    assertEquals(Kata.palindromization("123", 4), "1221");
    assertEquals(Kata.palindromization("123", 5), "12321");
    assertEquals(Kata.palindromization("123", 6), "123321");
    assertEquals(Kata.palindromization("123", 7), "1231321");
    assertEquals(Kata.palindromization("123", 8), "12311321");
    assertEquals(Kata.palindromization("123", 9), "123121321");
    assertEquals(Kata.palindromization("123", 10), "1231221321");
    
}

} // No opening curly brace
}

Thanks for clarifying that. My code is not checking for that, I need to go and fix it.

Thanks for gettin back to me joh_pot. Can I clarify something regard the instructions.
The function should only return 1 only if the first number contains straight triple and second number contain straight double of the same value digit
E.g.
(451999277, 41177722899) == 1 (num1 -triple 999s and num2 -double 99s)
(451999277L, 411777228L) == 0 (no double 99s in num2)

Hi joh_pot
The method arguments on test5 were different from yours for me. Originally it was this
assertEquals(0, TripleDouble(451999277L, 411777228L));

This was cause compile error because it was not call the static method correctly.

I have reset challenge and I am still not getting your method arguments. Below are the sample tests provide to me

import org.junit.Test;
import static org.junit.Assert.assertEquals;

public class Tests {

@Test
public void test1(){
  assertEquals(1, Kata.TripleDouble(451999277L, 41177722899L));
}

@Test
public void test2(){
  assertEquals(0, Kata.TripleDouble(1222345L, 12345L));    
}

@Test
public void test3(){
  assertEquals(0, Kata.TripleDouble(12345L, 12345L));
}

@Test
public void test4(){
  assertEquals(1, Kata.TripleDouble(666789L, 12345667L));
}

@Test
public void test5() {
  assertEquals(0, TripleDouble(451999277L, 411777228L));
}

}

This is for java 1.8.0_91(Java 8).

Java
test5 from sampleTest is incorrect. The static method is being called incorrectly and the expected result is wrong.
Should be correct to the below
@Test
public void test5() {
assertEquals(1, Kata.TripleDouble(451999277L, 411777228L));
}
otherwise test will always fail due compile-time error.
Joh_pot, you need to fix.
