1 PRACTICE PAPER-IP CONVERSION 1-Rewrite the code using switch.case. 2 int a=3; if(a= =3) System.out.println( Number is odd ); if(a= =7) System.out.println( Number is odd ); if(a= =5) System.out.println( Number is odd ); if(a= =4) System.out.println( Number is even ); System.out.println( Number is not ); 2-Rewrite the following program code using a Switch statement: 2 if( code == 1 ) Month = January ; if ( code == 2 ) Month = February ; if ( code == 3 ) Month = March if ( code == 4 ) Month = April ; Month = No Match ; 3-Rewrite the following program code using a Switch statement: 2 int a=1,b=1; if(a==0&& b==0) System.out.print("even numbers"); if (a==1&& b==1) System.out.print("odd numbers"); 4-Rewrite the following program code using a Switch statement: 2 char ch=tf1.gettext().charat(0); if(ch== a ch== A ) System.out.println("word starts with A or a" ); if(ch== b ch== B ) System.out.println("word starts with B or b" ); System.out.println("word starts with"+ch); 5-Rewrite the following program code using a Switch statement: 2 String Fruit=tf1.getText().toLowerCase(); char First=Fruit.charAt(0); char Last=Fruit.charAt(Fruit.length()-1); if(first=='c'&& Last== 't') System.out.println("Dry Fruit="+Fruit); if(first=='b'&& Last== 'y')

2 System.out.println("Berry="+Fruit); 6-Rewrite the following code using if statement without affecting the output of the code: 2 int a=1; switch (a) case 1: System.out.print( Sunday ); case 2 : case 3 : case 4 : case 5 : case 6 : System.out.print( WeekDay ); case 7: System.out.print( Nearing Weekend ); default : System.out.print( Wrong Number ); 7-Rewrite the following program code using switch statement: 2 String S=tf1.getText().toLowerCase(); if(s== a s== e s== i s== o s== u ) System.out.print( First alphabet is vowel ); System.out.print( First alphabet is not vowel ); 8-Rewrite the following code using if statement without affecting the output of the code:2 char branch = 'E'; // C - CSE, E - ECE, I - ITC int year = 2; switch( year ) case 1: System.out.println("English, Maths, Drawing"); case 2: switch( branch ) case 'C': System.out.println("Data structures, Java, Computer Organization"); case 'E': System.out.println("Micro processors, Logic switching theory"); case 'I': System.out.println("Drawing, Manufacturing Machines"); 9- Rewrite the following code using if statement without affecting the output of the code:2 int i = 0;

3 int j = 1; switch(i) case 0: switch(j) case 0: System.out.println("i is 0, j is 0"); case 1: System.out.println("i is 0, j is 1"); default: System.out.println("nested default case!!"); break default: System.out.println("No matching case found!!"); CONVERSION 1-Rewrite the following code using while loop and also specify the final value of A & B 2 int A = 50, B; for(b = 5; B<=18; B++) A+=B; JOptionPane.showMessageDialog(null, Value of A and B is +A+ +B); 2-Change the following code using for loop without affecting the out put: 2 int j=1,s=0; while ( j < 10 ) System.out.print(j); s = s + j; j + =3; System.out.print(s); 3. Rewrite the following program code using for loop: 2 int num=6; int temp=num; while(num>=1) temp=temp-1; if (temp%2==0) System.out.println( Is even ); System.out.println( Is odd ); num=num-2;

4 4- Rewrite the following program code using do while: 2 for(int i=0 ; i < 5 ; i++) System.out.println( i is : + i); 5- Rewrite the following program code using do while: 2 double Number = ;int R; for(int Firsr = 0, Second = 0; Number > 0; Number = Number / 10;) R = Number % 10; if ( R % 2 == 0 ) First += R; Second += R; System.out.print(First Second ); ERROR 1- Find the errors for the following program: 2 int i=0, int x=0; while(i<20) if(i%2=0) x=x + i System.out.print (x + "" ); i++; 2- The following code has some error(s). Rewrite the correct code underlining all the corrections made: 2 Int n1,n2=10; n1=n2-5; if(n1=n2) jtextfield1.settext("n1 and n2 are equal"); jtextfield2.settext("n1 and n2 values are" +n1+ " "+n2); jtextfield1.settext("n1 and n2 are not equal"); jtextfield2.settext("n1 and n2 values are" +n1+ " "+n2); 3-Identify the syntax errors and rewrite the java code by removing the syntax error(s) 2 int x=0; for(i=1; i<10; i++) for(int j=5; j>i ; j--) System.put.print( The j is + j) System.out.display( The i is + i);

5 X=i+j; System.out.print( The x is + x) 4-The following code has some error(s).rewrite the correct code underlining all the corrections made: 2 int SUM=0,Step=5; int I; For(i=0;i=<5;++i) Step+=5; Sum+=Step; jtextfield1.showtext(double.tostring(sum)); 5-Find out the errors, if any and underline the correction made 2 int i=0;x=0; while ( i < 10 ) if (i % 2 = 0) x == x + i ; system.out.print(x + 1); i ++; OUTPUT 1-Given a string object named salary having value stored in it obtain the 1 output of the following: JOptionPane.showMessageDialog(null, +salary.length( )+Integer.parseInt(salary)); 2-What will be displayed in jtextfield1 after executing the following code? 1 int m = 15; m = m + 1; if ( m < 15 ) jtextfield1.settext(integer.tostring(m)); jtextfield1.settext(integer.tostring(m+15)); 3-What will be the contents of jtextfield1 after executing the following statement : 1 int n=20; n=n-6; if(n<10) jtextfield1.settext(integer.tostring(n)); jtextfield1.settext(integer.tostring(n-2)); 4-What will be the contents of jtextfield after executing the following statement?1 jtextfield.settext ( B + a );
