I was asked to write a java program that prints all the multiples of 3 between 30 and 70 using

a.. while loop

b... do...while loop

c... for loop

Thanks

next

while.. loop
int i = 33;
System.out.println(i);
while(i<70){
System.out.print(" "+i);
i += 3;
}

do....While Loop
int i = 33;
System.out.println(i);
do{
System.out.print(" "+i);
i += 3;
}while(i<70);

Thanks brother.. what of for loop?

for(int i=33; i<70; i+=3){
System.out.print (" "+i);
};

What about making some decision?
while.. loop
int i = 33;
System.out.println(i);
while(i<70){
If(i % 3 ==0){
System.out.print(" "+i);
}i ++;
}
do....While Loop
int i = 33;
System.out.println(i);
do{
If(i % 3 ==0){
System.out.print(" "+i);
}i ++;
}while(i<70);

For loop
For(int i =33;i<=70){
If(i % 3 ==0){
system.out.println(i);
}
}

There is a reason it is called an ASSIGNMENT!

Find out on your own, the features of the various loop structures.

n

There should not be semicolon after your closing brace

ahmmyreal:
for(int i=33; i<70; i+=3){
System.out.print (" "+i);
};

Factorials are used frequently in probability problems. The factories of a positive integer n (written n! And pronounced "n factorial" ) is equal to the product of the positive integers from 1 to n. Write a program that read an integer number, evaluates and display its factorial .

(2) Write a program that reads ten (10) positive integers values from user; calculate and print their Mean.
Hints : Mean x bar = summation fx / n thanks as I would be very happy to get the answer .

Nobody to give me clue ?

@OP: at least make some effort, and show where you are stuck.

for (int i = 30; i <= 70; i++)
{
if (i%3 == 0) { // if the remainder of dividing i by 3 is 0, modulo operator...
System.out.println(i); //then print i on a new line.
}
}

System.out.println(i);
while(i<70){
System.out.print(" "+i);

}

do....While Loop

System.out.println(i);
do{
System.out.print(" "+i);
i += 3;
}while(i<70);

why are you looping from 33, and not 30?

Its still the same, since he has already declared i=33

This looks like C, any why didnt you bring the comment to another line instead of enclosing in a bracket, anyway i don't know how to use java.

is it? Considering that the question said to print from 30? If it is, when would 30 ever be printed?

none of the two comments is enclosed in a bracket. Those are valid comment syntax, but you can write it anyhow you find to be more readable. In a case where it's a comment for a single line of code, the above is more commonly used. That is Java, not C. Most OOPs do look alike.
