 For loop, Do….While Loop and While
Loop
Coding:
private voidcontinueActionPerformed(java.awt.event.ActionEventevt) {
int t;
t=Integer.parseInt(P.getText());
A.append("Numbersare ...... n");
for(inti=1;i<=t; i++)
{ A.append(""+i + "n"); }
int n=1;
do{
B.append("");
B.append(""+n+"n");

n++;
} while(n<=t);
intu=1;
while(u<=t){
C.append("");
C.append(""+u+"n");
u++;
}
}

 FIBONACCISERIES
Coding:
private voidokActionPerformed(java.awt.event.ActionEventevt){
intt;
t=Integer.parseInt(a.getText());
intf1, f2=0, f3=1 ,f4 = 0;
b.setText("");
for(inti=0;i<t;i++)
{ if(i==0)
{ b.append("0"+"n"); }
else
{ f1=f2+f3;
f3=f2;
f2=f1;
f4=f4+f1;
b.append(""+f1+"n");
} }

JOptionPane.showMessageDialog(null,"Sum="+f4);
}
private void clrActionPerformed(java.awt.event.ActionEventevt) {
a.setText("");
b.setText(""); }

 CombinationFormula
Coding:
private voidcombinationActionPerformed(java.awt.event.ActionEventevt) {
intn,m;
n=Integer.parseInt(A.getText());
m=Integer.parseInt(B.getText());
inti,j=1;
for(i=1;i<=n;i++)
{ j=j*i; }
ints,t=1;
for(s=1;s<=m;s++)
{ t=t*s; }
intp; p=n-m;
intk,l=1;
for(k=1;k<=p;k++)
{ l=l*k; }
intres;
res=j/(t*l);
c.setText(""+res);

}
private void clearActionPerformed(java.awt.event.ActionEventevt) {
A.setText(""); B.setText("");
c.setText(""); }

 SUM OF TWONUMBERS USING
INPUTMETHOD

Coding:
private voidclickmeActionPerformed(java.awt.event.ActionEventevt) {
int a, b,c,d;
Strings,t;
s=JOptionPane.showInputDialog("EnterfirstNumber");
t=JOptionPane.showInputDialog("EntersecondNumber");
a=Integer.parseInt(s);
b=Integer.parseInt(t);
c=a+b;
JOptionPane.showMessageDialog(null,"The sumof twonumberis:" +c);
}

 HighestNumberUsingConditional
Operator
Coding:
private voidclearActionPerformed(java.awt.event.ActionEventevt) {
A.setText("");
B.setText("");
C.setText("");
}
private void okActionPerformed(java.awt.event.ActionEventevt) {
int a, b;
a= Integer.parseInt(A.getText());
b= Integer.parseInt(B.getText());
intc;
c= a>b?a:b;
C.setText("The highestnumberis:" +c);
}
System.exit(0); }

 Factorial
Coding:
double n;
n= Double.parseDouble(A.getText());
double i,j=1;
for(i=1;i<=n;i++)
{
j*=i;
}
B.setText(Double.toString(j));
}
A.setText("");
B.setText("");
}

 PrimeNumber
CODING:
private voidexitActionPerformed(java.awt.event.ActionEventevt) {
System.exit(0); }
a.setText("");
b.setText("");
}
private void primenoActionPerformed(java.awt.event.ActionEventevt) {
int A,i;
for(i=2;i<=A/2;i++)
{
if(A%i==0)
{
break;
}
}
if(i>A/2)
{
b.setText("Itisprime number");

}
else
{
b.setText("Itisnotprime number");
}

 The Given Number Is Magic Number
Or Not
CODING:
inta = 0,b=1,c=0,d;
a=Integer.parseInt(A.getText());
d=a;

inti=a;
while(d>0)
{ b *= d%10; d/=10;
c += i%10; i/=10;
}
B.setText("Sumof digit"+a+ " is: " + c);
C.setText("Productof digit"+a+ " is : " + b);
inte;
e=b+c;
D.setText(""+e);
if(a==e)
JOptionPane.showMessageDialog(null,"ThegivennumberisMagicNumber");
else
JOptionPane.showMessageDialog(null,"Thegivennumberis notMagic Number");
}

 ShortName
CODING:
Stringf , m , l , s=" ";
f = a.getText().substring(0,1);
m =b.getText().substring(0,1);
l= c.getText();
s = s.concat(f);
s=s.concat(". ");
s= s.concat(m);

s=s.concat(". ");
s=s.concat(l);
s = s.concat(" ");
d.setText(s);
}
