Code Sample 1

int i;
for(i = 0; i < 10; i++)
{
}

solution

        
            
int i = 0;
while(i < 10)
{
  i++;
}

Code Sample 2

int i=1;
int d=5;
while(i<=5)
{
  d=d*2
  System.out.println(d);
  i++;
}

solution

        
            
for(int i=1, d=5; i<=5; i++)
{
  d = d * 2;
  System.out.println(d);
}

Code Sample 3

for(int m=5, n=10; n >=1; n--)
{
  System.out.println(m*n);
}

solution

        
            
int m = 5, n = 10;
while (n>=1)
{
  System.out.println(m * n);
  n--;
}

Code Sample 4

int s=0;
for(int x=1; x<=25; x+=2)
  s+=x;

solution

        
            
int x=1,s=0;
while (x<=25){
  s +=x;
  x+=2;
}

Code Sample 5

int x,c;
for (x=10, c=20; c>=10; c = c - 2)
  x++;

solution

        
            
int x=10,c=20;
while(c>=10)
{
  x++;
  c=c-2;
}
