Problem in using Tips_Create Global Variables on the fly

Product Forums Tips & Tricks

i can find this block of code under katalon tips/tricks. I need some help in using this.

void addGlobalVariable(String name, def value) {
MetaClass mc = script.evaluate("internal.GlobalVariable").metaClass
String getterName = "get" + name.capitalize()
mc.static."$getterName" = { -> return value }
//mc.static."$name" = value
}

Question:

1. Do we need use this block code as @keyWord? or under any existing class or By creating new Class?

2. when I am using this code. Inside any class. I can see error near void keyword.

public class ThisMain{
public static void main(String[] args){
void addGlobalVariable(String name, def value) {
MetaClass mc = script.evaluate("internal.GlobalVariable").metaClass
String getterName = "get" + name.capitalize()
mc.static."$getterName" = { -> return value }
//mc.static."$name" = value
}
}
}
