Java Logics: If else, for, foreach, while and do while

If-Else

if (age >= 18) {
    System.out.println("Adult");
} else {
    System.out.println("Minor");
}

For Loop

for (int i = 0; i < 5; i++) {
    System.out.println(i);
}

Foreach Loop

for (String item : items) {
    System.out.println(item);
}

While and Do-While

A while loop checks its condition before running; a do-while loop runs its body at least once before checking the condition.

while (count < 5) { count++; }
do { count++; } while (count < 5);
