The code you've provided is written in Java. It seems like you want to understand what this code does. However, there is a small mistake in the code. The method `m(int i)` should be static because it's called from a static context (the `main` method). Also, the quotation marks around the comma in the `println` statement are not standard. Here is the corrected code:

```java
public class testmeth {
static int i = 1;

public static void main(String args[]) {
System.out.println(i + ", ");
m(i);
System.out.println(i);
}

public static void m(int i) {
i += 2;
}
}
```

Now, let's go through the code step by step:

1. The class `testmeth` is defined with a static integer variable `i` initialized to 1.

2. The `main` method is the entry point of the program. It first prints the value of `i` followed by a comma. At this point, `i` is 1, so it prints "1, ".

3. Then, it calls the method `m(i)`, passing `i` as an argument.

4. Inside the `m` method, the passed argument `i` is incremented by 2. However, this change does not affect the static variable `i` in the class because Java is pass-by-value, meaning that it passes a copy of the variable, not the original one.

5. After the `m` method is finished, it goes back to the `main` method and prints the value of `i` again. Since `i` was not changed by the `m` method, it still prints "1".

So, the output of the program will be:

```
1,
1
```
