Problem coding a for loop with Dr. Java?

Question

I am trying to make a code that sums the first 10 positive integers using a for loop. But when I attempt to compile
for(int i=0; i<10; i++){
it comes up with an error saying it expects a class or interface.

My teacher is making us use for loops just to learn how to do it

Answer 1

That's not the right approach or even the correct code.

Try something that looks like sum = sum + i;

public class Sum {

int i;
int sum=0;

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

sum = sum + i;
}

System.out.printf()
}

As the other poster mentioned - do you know what a Java class structure looks like? Are you aware of what a Java program consists of:

Answer 2

O it rather is straightforward seem interior your for assertion the place you have x+=index so on the 1st loop x = 0 and index = 0 2nd loop x=0 index = 2 output = 2 third loop x = 2 index = 4 output = 6 do you notice it yet?

Answer 3

Besides the class laid out in the previous responses, you're going to need a "main" method too. You can find basic tutorials in the link below.

Answer 4

In Java, all code should belong to a class.

Try something like

public class MyClass {
...
}
