2. Two Classes used to read user input 1.Scanner 2.BufferedReader 3.StringReader 4.1 and 2 5.1 and 3

3. The BufferedReader may throw the following exception 1.InputMismatchException 2.StringOutOfBoundsException 3.NumberFormatException 4.IndexOutOfBoundsException 5.None

4. The Scanner may throw the following exception 1.InputMismatchException 2.StringOutOfBoundsException 3.NumberFormatException 4.IndexOutOfBoundsException 5.None

5. Integer.parseInt throws the following exception 1.InputMismatchException 2.StringOutOfBoundsException 3.NumberFormatException 4.IndexOutOfBoundsException 5.None

6. String s = “JAVA”; int x = s.charAt(-1); returns 1.InputMismatchException 2.IndexOutOfBoundsException 3.NumberFormatException 4.Nothing, it is blank 5.None of the above This slide changed to fix a typo

7. String s = “JAVA”; int x = s.charAt(2); returns 1.InputMismatchException 2.A 3.V 4.StringOutOfBoundsException 5.Nothing, it is blank 6.None of the above

9. if(i 25) 1.True for all numbers between 20 and 25 2.True for all numbers between 21 and 24 3.True for all numbers less than 20 and greater than 25 4.Never True

10. if(i>20||i<25) 1.True for all numbers less than 20 and greater than 25 2.True for all numbers between 21 and 24 3.True for all numbers 4.Never true

11. if(i>20&&i<25) 1.True for all numbers less than 20 and greater than 25 2.True for all numbers between 21 and 24 3.True for all numbers 4.Never true

12. How many times will the loop execute? for(i=0; i<5; i=i+2){ 1.Will never execute 2.Will execute 2 times 3.Will execute 3 times 4.Will execute 4 times 5.Infinite Loop

13. How many times will the loop execute? for(i=0; i>5; i=i+2){ 1.Will never execute 2.Will execute 2 times 3.Will execute 3 times 4.Will execute 4 times 5.Infinite Loop

14. How many times will the loop execute? for(i=0; i>5; i=i-1){ 1.Will never execute 2.Will execute 2 times 3.Will execute 3 times 4.Will execute 4 times 5.Infinite Loop

15. How many times will the loop execute? int x = 2; while(x<5){ x=x+(x%2); } 1.Will never execute 2.Will execute 2 times 3.Will execute 3 times 4.Will execute 4 times 5.Infinite Loop

16. How many times will the loop execute? int x = 3; while(x<5){ x=x+(x%2); } 1.Will never execute 2.Will execute 2 times 3.Will execute 3 times 4.Will execute 4 times 5.Infinite Loop

17. How many times will the loop execute? int x = 18; while(x>5){ x=x-(x/3); } 1.Will never execute 2.Will execute 2 times 3.Will execute 3 times 4.Will execute 4 times 5.Infinite Loop

18. Switch statements work with 1.int 2.char 3.String 4.doolean 5.Any primitive data type 6.Only 1 and 2 7.Only 1,2 and 3

19. switch(x){ case 1: case 2: case 3: x=x+1; case 4: x=x+2; default: x=x-5; } Runing this code with x = 2, After executing the switch statement What will be the value of x? 1.2 2.3 3.4 4.5 5.0

20. switch(x){ case 1: x=x+1; break; case 2: x=x+2; break case 3: x=x+1; break; default: x=x-5; } Runing this code with x = 7, After executing the switch statement What will be the value of x? 1.2 2.3 3.4 4.5 5.0

21. switch(x){ case 1: x=x+1; case 2: x=x+2; break case 3: x=x+1; default: x=x-5; } Runing this code with x = 2, After executing the switch statement What will be the value of x? 1.2 2.3 3.4 4.5 5.0

22. switch(x){ case 1: x=x+1; case 2: x=x+2; break case 3: x=x+1; default: x=x-5; } Runing this code with x = 1, After executing the switch statement What will be the value of x? 1.2 2.3 3.4 4.5 5.0

23. String s1=“JAVA”; String s2=“javA”; boolean areEqual=false; areEqual =s1.equals(s2); areEqual is: 1.True 2.False
