Program? 4. What are Keywords? Give two examples of keywords available in Java. 5. What is the difference between = and == operator in java? 6. What is the purpose of „break‟ statement in java? 7. What is the difference between entry controlled and exit controlled loop 8. Evaluate the following expressions separately in Java. Assume all variable to be integers and

initial value of a as 10 and b as 20 a. x = a++ + b++; b. x= ++a + ++ b; c. x= ++a + b++; d. x = a / b % b; e. x= b / a % b; f. x = b + a++ % b; g. x = a+ b *a * b;

9. What would be output of the following code segment written in java. public static void main(String [] args) { int a=10, b= 9; boolean x; x = a++ == ++b; System.out.print("x = "+x); }

10. Find the output of the following code snippet written in java public static void main(String []args) { int x=10, y=5; System.out.println(x++); System.out.println(++y); System.out.println((x++ + ++y));

System.out.println((++x - y++)); System.out.println((x++) + (++y)); System.out.println((++x)-(y++)); System.out.println((x++) + (++x)); System.out.println("x = "+ X +" y="+ y); } 11. Find the output of the following code snippet written in java public static void main(String args[]) { int no1=2,no2=1,i; while(no2<=3) { i=no1; while(i<=no2) { no1=no1*i; i++; } System.out.println("No1 "+ no1); System.out.println("No2 "+ no2); no2++; } } 12. Find the output of the following code segment written in JAVA. Assume all necessary header files have been included and ignore any syntax error if any. public static void main(String [] args) { int i = 3, a=0, b=1, n=5, c; System.out.print(a+ “ “+b+” “); while ( i < n) { c= a + b; System.out.print(c+” “); a = c - a; b = c; i++; } } 13. How many times will the following loop get executed and what will be the final value of the variable I after execution the loop is over. int I = 5; do { I += 3; System.out.println("I = "+I); I = I + 1; } while (I >= 9); 14. Correct the errors in the following program segment written in JAVA. You are just required to write the corrected code, underlying the corrections made. Public Static Void Main (String [] args) { Integer Nos = 100;

while (Nos => 45) { If (Nos % 5 = 0); Nos+=10; otherwise Nos + = 20; } } 15. Convert the following „while loop‟ into its equivalent „for loop without altering the output of the program. int x = 100, a = 30; while ( x>= 10) { System.out.println(”New Amount =”+(x + a)); a++; x - = a; } 16. Text entered in a jtextField is of String type. A programmer wants to store it in a variable of type integer. Is it possible how? Explain. 17. Explain the following string functions available in Java giving suitable examples in each case: a. Length ( ) b. substring ( ) c. concat ( ) d. trim ( ) e. toString ( ) f. toUpperCase ( )
