Question

I noticed that java (hence probably C) has no problem with this:

while(condition1) {
    //do somethin'
} while(condition2);

Is this the same as:

while(condition1 && condition2) {
    //do somethin'
}

Answer 1

No, you have two loops.

while(condition1) {
  // do something
}

while(condition2); // second loop which does nothing.

The second loop is the same as

while(condition2) { }

EDIT: My suggestion is to use the automatic formatter in your IDE regularly. Otherwise you can create formatting which suggests the code does things it doesn’t.

example 1

if (condition)
    statement1;
    statement2;
statement3;

In this example, it appears that the first two statements are part of the if condition, but only the first is.

example 2

statement;

Doesn’t look like legal Java, but it is, not for the reasons the formatting suggests 😉
