Predict the Output of the following Java program:

class dk3
{
public static void main(String args[])
{
int m=2,n=15; 
for(int i=1;i<=5;i++)
{
m++;--n;
System.out.println("m="+m);
System.out.println("n="+n);
}
}
}

Determine how many times the body of the loop will be executed and predict the output.

class dk4
{
public static void main(String args[])
{
int x=5,y=50; 
while(x<=y)
{
y=y/x;
System.out.println(y); 
}
}
}

Rewrite the following program using do while:

class Pattern
{
public static void main(String args[])
{
int i,j; 
for(i=5;i>=1;i--)
{
System.out.print(i);
}
System.out.println();
} 
}

Rewrite the following program using do while:

class Number
{
public static void main(String args[])
{
int i,n=191,c=0; 
for(i=1;i<=n;i++)
{
if(n%i==0) 
c=c+1;
}
if(c==2)
System.out.println("Prime"); 
else
System.out.println("Not Prime");
} 
}
