String str = new String(“Snow!”);
int i = 0;
for (; i < str.length(); ++i) {
  System.out.print(“Char #” + ++i + “ is ” + str.charAt(i));
  i += ++i;
  break;
}
System.out.println(" " + i++);

Consider the following JAVA code snippet:

String
 txt = "Fun with loops!";
char
 letter;
for(int
 i =0; i < txt.length()-1; i++)
{
  letter = txt.charAt(i + 1);
  if
(i % 2 == 0)
	System.out
.print(txt.charAt(i));
  else
	System.out
.print("-");
  System.out
.print(letter);
}

Determine the output of the following JAVA code snippet:

int x = 4, y = 1;
while(x > 0) {
     y = 1;
     while (y < x) {
          System.out.print(x + "" + y + " ");
          y++;
     }
     x--;
}

What is the output of the following piece of code:

int x = 5;int total = 0;
while(x++ < 10)      total +=x;   System.out.println(total);
