Answer 1

2.
class Factor
{
static void main(int n)
{
int i;
for(i=1; i<=n; i++)
{
if(n%i==0)
{
System.out.print(i);
}
}
}
}
3.
class Factorial
{
static void main(int n)
{
int i, m=1;
for(i=1; i<=n; i++)
{
m=m*i;
}
System.out.print(m);
}
}
4.
class Table
{
static void main(int n)
{
int i, m=0;
for(i=1; i<=10; i++)
{
m=n*i;
System.out.print(i+"*"+n+"="+m);
}
}
}
5.
class Days
{
void main(int n)
{
switch(n)
{
case 1:
System.out.print("31 days");
break;
case 2:
System.out.print("28 days or 29 days");
break;
case 3:
System.out.print("31 days");
break;
case 4:
System.out.print("30 days");
break;
case 5:
System.out.print("31 days");
break;
case 6:
System.out.print("30 days");
break;
case 7:
System.out.print("31 days");
break;
case 8:
System.out.print("31 days");
break;
case 9:
System.out.print("30 days");
break;
case 10:
System.out.print("31 days");
break;
case 11:
System.out.print("30 days");
break;
case 12:
System.out.print("31 days");
break;
default:
System.out.print("this number month does not exist");
}
}
}
