This is the another half of the fifth part. Here are the solutions for the challenges.
Half pyramid
You are only allowed to use 2 for-Loops. Now just think logically and you get following code:
for(int i = 0; i <= 10; i++){
for(int j = 0; j <= i; j++){
System.out.print("t ");
}
System.out.println();
}
Easy counter
In this task, you were only allowed to use 1 while-Loop and it counts as high as you want. This is very easy too:
int x = 0;
while(x <= 10){
System.out.println(x);
x++;
}
Sphere surface to radius
This is very tricky, especially for beginners. The code for this should look like this:
double o = 10;
if(o <= 0.0){
System.out.println("ERROR: o is too small");
}else{
System.out.println("Calculating the radius out of o");
System.out.println("-./(o / (4PI))\\");
System.out.print("-./( " + o + " / (4PI))\\ = ");
System.out.println(Math.sqrt(o/(4*Math.PI)));
}

Remember: I'm not a genius too! I'm 16 years old but I know quite a lot, because Java or programming in general is fascinating me so much (and yes I have friends and other hobbies :)). So don't give up! Follow you dreams and in some day, they will get true.
