Q1. To find Volume of Cube & Cuboid
private void volumeActionPerformed(java.awt.event.ActionEvent evt) {
int ch,lngt,brdt,high,cvol,cbdvol;
ch=Integer.parseInt(chc.getText());
lngt=Integer.parseInt(lng.getText());
brdt=Integer.parseInt(brd.getText());
high=Integer.parseInt(hgh.getText());
cvol=lngt*lngt*lngt;
cbdvol=lngt*brdt*high;
switch (ch) {
case 1: lbl.setText("That's a Cube");
result.setText("its perimeter is "+cvol);
break;
case 2: lbl.setText("That's a Cuboid");
result.setText("its perimeter is "+cbdvol);
break;
default:lbl.setText("Please Enter a valid Choise. i.e. 1 or 2");}
2. To find area of shapes
private void areaActionPerformed(java.awt.event.ActionEvent evt) {
float ss,recl,recb,cirr,sqra,reca,cira;
float pi=22/7;
ss=Float.parseFloat(sqs.getText());
recl=Float.parseFloat(rl.getText());
recb=Float.parseFloat(rb.getText());
cirr=Float.parseFloat(rc.getText());
sqra=ss*ss;
reca=recl*recb;
cira=pi*cirr*cirr;
sqa.setText(""+sqra);
ra.setText(""+reca);
ca.setText(""+cira);}
3. To find Factorial of number
private void factActionPerformed(java.awt.event.ActionEvent evt) {
int num,result=1,i;
num=Integer.parseInt(t1.getText());
for (i=1;i<=num;i++){
result=result*i;
t2.setText(""+result);
4. To check a number is prime or Composite
class PrimeNo{
public static void main(String args[]){
int num = Integer.parseInt(args[0]);
int flag=0;
for(int i=2;i<num;i++){
if(num%i==0)
System.out.println(num+" is a Composite NUmber");
flag = 1;
break;}
if(flag==0)
System.out.println(num+" is a Prime Number");
5. To find Largest of 3.
private void largestActionPerformed(java.awt.event.ActionEvent evt) {
int n1,n2,n3,lrg;
n1=Integer.parseInt(num1.getText());
n2=Integer.parseInt(num2.getText());
n3=Integer.parseInt(num3.getText());
if (n1>n2&&n1>n3)
res.setText(""+n1);
else if (n2>1&&n2>n3)
res.setText(""+n2);
else
res.setText(""+n3);
6. To find grades.
7. WAP to find the reverse of number
public static void main(String[] args) {
int num,reverse=0;
Scanner input=new Scanner (System.in);
System.out.print ("enter a number :");
num=input.nextInt();
while (num!=0){
reverse = reverse*10;
reverse = reverse +num%10;
num=num/10;
System.out.print ("reverse of input number is : "+reverse+"\n");
8. To find Sum of Digits of Numbers
class DigitSum
public static void main(String args[])
int i,a=0, sum=0;
i=Integer.parseInt(args[0]);
while(i!=0)
a=i%10;
i=i/10;
sum=sum+a;
System.out.println(sum);
9. To find Prime Numbers Between 2 to 100
public static void main(String[] args) {
int i ;
int num ;
String primeNumbers="";
for (i = 2; i <= 100; i++){
int counter=0;
for(num =i; num>=1; num--){
if(i%num==0){
counter = counter + 1;
if (counter ==2){
primeNumbers = primeNumbers + i + " ";
System.out.println("Prime numbers from 2 to 100 are :");
System.out.println(primeNumbers);
10. To find Sum of 10 even numbers
public static void main(String[] args) {
int num=0,i=0;
Scanner input=new Scanner (System.in);
for (i=1;i<=10;i++){
System.out.print ("enter a number :");
num=num+input.nextInt();
System.out.println("the sum of all 10 numbers are "+num);
11. a)Select all NonMedical Students.
Select * from Student1 Where Stream="NonMedical";
b) List name of those students who are in class 12 order by Stipend.
Select Name from Student1 Where Class like "12%" Order by Stipend;
c) List all Students Sorted by AvgMark.
Select * from Student1 Order by AvgMark desc;
d) Display a Report, Listing Name, Stipend, and Stream. (Stipend*12)
Select Name, Stipend*12,Stream from Student1;
