XIIC-IP MAY 2013 ASSIGNMENT/HOME WORK for Summer Vacation
1.Rewrite
the following code fragment using do-while loop and also give output :
for(int i=1;i<=10;i++)
{
System.out.println(“”+i);
}
2. How many times
will each of the following loops execute? Which one of these is an entry
control loop and which one is an exit control loop?
Loop1:
int sum = 0, i = 5;
while (i<5)
{sum += i;i++;}
Loop2:
int sum = -30, i = -5;
do
{ sum += i;i++;} while (i<5);
3. What will be the content of jTextField1 after executing the following
code:
int Num = 6;
Num -= 3;
if ( Num > 5)
jTextField1.setText(Integer.toString(Num));
else
jTextField1.setText(Integer.toString(Num+5));
4. What will be the contents of jTextArea1 after executing the following
statement:
jTextArea1.setText("Object\nOriented\tProgramming\n In Java");
5. Rewrite the following program code using
switch statement:
int d; String day;
if (d == 1)
day = "Monday";
else if (d == 2)
day = "Tuesday";
else if (d == 3)
day = "Wednesday";
else day = "-";
6. The following code has
some error(s). Rewrite the correct code underlining all the corrections made:
int i=2; j=5
while j>i
{jTextField1.gettext("j is
greater");
j--;++i;}
joptionPane.ShowMessageDialog("Hello");
(Hint:

Application)
8. Rewrite
the following code using While LOOP
i=2;
do
{
System.out.println(i);
i+=2;
}
while(i<50);
9. Find the output of the following code if
ch=’B’
switch(ch)
{
case ‘A’ : System.out.println( ‘A’);
case ‘B’
: System.out.println(‘B’);
case
‘C’ : System.out.println(‘C’);
break;
case ‘D’
: System.out.println(‘D’);
default
: System.out.println(‘F’);
}
10.The following code has some
error(s). Rewrite the correct code underlining all the corrections made.
Int y==3;
Switch(y);
{
Case= 1 : System.out.print(“Yes its One”)
break;
Case>=2
: System.out.println(“Yes its more than Two”)
break;
case else
: System.out.print(“Invalid Number);
Break;
}
11.The following code has some error(s).
Rewrite the correct code underlining all the corrections made: int
a, b=20;
DO
{ a=b*2;
b=a/b;
}While(b>40)
12.What will be the output of the following
code fragment if the value of ch is ‘a’
switch(ch) { case ‘a’ : System.out.println(“it is a.”);
case ‘b’ : System.out.println(“it is
b.”);
case ‘c’ : System.out.println(“it is
c.”);
break;
case ‘d’ : System.out.println(“it is
d.”);
break;
default : System.out.println(“not a b c d.”);
}

13.Write the output of the following code
|
|
int j =
10,x=0,i=0;
for (i =
1;i<=10;i++)
{
if(i%2==0)
x = x+ (i * j);
j = j – 2 ;
}
System.out.println(x);
|
14. Rewrite
the folowing code to for loop
int f=1,I=2 ;
while(++I <5)
f*=I ;
System.out.println(f);
15.Rewrite
the code after making correction. Underline the corrections.
int sum; value ; inct;
int i;
for (i==0,i<=10; i++)
sum+= I;
inct ++;
16.What will be the output
of the following code
int I = 3 , n =0 ;
while ( I < 4)
{ n++ ; I -- ;
}
System.out.println( n
);
17.Convert the following segment into an
equivalent do loop.
int x, c;
for (x=10, c=20; c>=10; c=c-2)
x++;
18.What will be the output of following
segment?
int i, j, k, x=0;
for (i=0; i<5; ++i)
for (j=0; j<i; ++j)
{
k=(i+j-1);
if (k%2==0)
x+=k;
else
if (k%3==0)
x+=k-2;
System.out.print(x+” ”);
}
