Review comment:
Actually, at least Java 8 rewrites for-each loop for array into the for-i
loop, here is an example of the source code and decompiled code:
```
String[] arr = {"a", "b", "c"};
for (String x : arr) {
System.out.println(x);
}
```
code after decompilation:
```
String[] var1 = new String[]{"a", "b", "c"};
String[] var2 = var1;
int var3 = var1.length;
for(int var4 = 0; var4 < var3; ++var4) {
String var5 = var2[var4];
System.out.println(var5);
}
```
But anyway, this is a minor comment, so the code may be left as it is.
