Rewrite the following for loop by using while and do-while loops:

int a=37, b, c=0;
for(b=1;b<=a;b++)
{
    if (a % b == 0)
        c = c + 1;
}
if(c == 2)
    System.out.println(a + " is a prime number"); 
else
    System.out.println(a + " is not a prime number");

Rewrite the following using for loop:

int i = 1, f = 1;
do
{ 
f=f*i;
i++;
} 
while(i<=10);
System.out.println(f);

State the final value of q at the end of the following program segment after execution. Show the dry run.

for(m=2;m<=3;++m)
{
for(n=1;n<=m;++n)
{
p=m+n-1;
if(p%3 == 0)
q += p;
else
q += p+4;
}
}

Write the following statement using switch case construct.

if (a==1)
{
b += 10;
System.out.println(b);
}
else if (a == 2)
{
b -= 10;
System.out.println(b);
}
else
{
b *= a;
System.out.println(b); 
}
