True or False (Java programming)?

Question 1 True False code must explicitly call the garbage collector method and must call it frequently; otherwise your program will be overrun with garbage objects! The following for loop and while loop are equivalent: for (INITIALIZER: CONDITION INCREMENTOR) INITIALIZER while (CONDITION) BODY INCREMENTO The following pieces of code are equivalent: a[N++] item and N s N 1 CNJ item Int Stack s new Intstacko s Push (s) Int stack t si s pop(); At this point t is not empty. String a "Ping"; String b "Pong"; evaluates to true. Then (a b PingPong")

Explanation / Answer

1. Both for and while loops are same. In for loop, firstly value is initialized and condition is applied and then for loop will execute the body and increment the value. Similarly whe loop also do the same. So they both are equivalent.

2. In first code, incremented value is assigned in item. And in later code, N is incremented and then its value is assigned in item.

3. In this code, 5 is put in stack and its value is assigned in t and then stack's value is popped out. So, 5 will be deleted from stack.

4. String A is ping and string B is pong. a+b means concatenation. When a and b are concatenated it forms pingpong. So, it is true.
