Question

What is printed out by the following code fragment?

int n = 15;
A) if ( 10 <= n && 20 <= n ) { System.out.println( "A" ); } else { System.out.println( "B" ); }
B) if ( 10 < n || 20 < n ) { System.out.println( "C" ); } else { System.out.println( "D" ); }
C) if ( n != 15 ) { System.out.println( "E" ); } else { System.out.println( "F" ); }
D) if ( n == 15 ) { System.out.println( "G" ); } else {
E) if ( n > 0 ) { System.out.println( "H" ); } }

Answer 1

The following code will return the Output is:

B

C

F

G

Explanation:

A.) In the first option, n is greater than 10 and n is less than 20.

so, the condition of the if statement goes false and else will be executed and it print B.

B.) In the second option, n is greater than 10 or n is less than 20.

so, the condition of the if goes true and else part will not be executed and it print C.

C.) In the third statement, n is equal to the 15.

so, the condition of the if statement goes false and else part will be executed and it print F.

D.) & F.) In the last two statements, n is equal to the 15.

so, the condition of D option goes true and else part of option E will not be executed and it prints G.
