class So
public static void main(String args[])
{
String s="Hello, world";
for(int i=0;i<s.length;i++)
{
System.out.println(s[i]);
System.out.print(s[i]+" ");
}
}

Please use:

prime viperBOT
#

Please use this format for posting code:

```java
// Example java program
int value = 5;
System.out.println(value);
```

Which results in:

// Example java program
int value = 5;
System.out.println(value);

For syntax highlighting, you have to add the name of the language after the three backticks, like ```java. Please make sure to use exactly this format, so no space between the backticks and the language name, and a newline before the code starts. If done right, the syntax highlighting will even be applied to your text as you type, before sending.

And you dismissed the chatgpt reply which contained the answer.

#

length is a function, not a property.

MOOC is a completely free introductory Java course created by the University of Helsinki, it is a great way to learn Java from the ground up.

It consists of two parts, one at beginner, and another at intermediate level. The end of the course is marked by creating your own Asteroids game clone!

Even though the instructions show how to configure and use NetBeans for the course, you can use IntelliJ. To use IntelliJ, simply install the TMC plugin by opening IntelliJ -> File -> Settings -> Plugins and searching for TMC. You will then be able to use IntelliJ to complete MOOC.

(the course is available in both English and Finnish)

In java, strings are objects that you need to call methods on to do things with them

#

length() function instead of just the length property

#

And I'm not sure if you can do s[]

#

You'd need to do s.charAt()

half zenith
#

It's charAt() rather than an array accessor as well.

#

You can also just do:

String s="Hello, world";
for(String letter : s.split(""))
{
    System.out.println(letter);
    System.out.print(letter + " ");
}
