 for(int i =1;i<=number;i++) {
     result*=i
 }
 System.out.println("Result=" + result);

while

int result = 1;
int counter=1;
while(counter<=number){
    result*=counter;
    counter++;
}
System.out.println("Result=" + result);

do···while

int result = 1;
int counter = 1;
do{
result*=counter;
counter++;
}while(counter<=number);
