Q: What is the output of the Java program?
String name1="FOX", name2="DOG";

  System.out.println("DINO");
A. FOX DINO
B. FOX GOOD DINO
C. Compiler error
D. None

Q: What is the output of the Java program with IF-ELSE-IF statements?
int marks=55;
if(marks >= 80)
  System.out.println("DISTINCTION");
else if(marks >=35)
  System.out.println("PASS");
else
  System.out.println("FAIL");
A. DISTINCTION
B. PASS
C. FAIL
D. Compiler error
Solution: no solution
Q: What is is the output of the Java program?

  System.out.println("PASS");
A. DISTINCTION
B. PASS
C. Compiler error
D. None
Solution: It is ok to skip the ELSE statement.

  System.out.print("FOREST ");
  System.out.println("AMAZON");
else
  System.out.println("UNKNOWN");
A. TOWN
B. FOREST AMAZON
C. UNKNOWN
D. Compiler error
Solution: ELSE-IF statement should not contain more than one statement without braces { }.
Q: What is the output of the Java program?
int marks=29;

System.out.println("RANK");
A. RANK
B. PASS
C. PASS RANK
D. Compiler error 
Solution: Notice the immediate Semicolon (;) after the IF. It ends the IF block. So whatever is next or below it will be executed always.
