class x{
public static void main(String[] args){
String x="<html><head></head></html>";
String arr[]=x.split("<head>");
String script="hi";
x=arr[0]+"<head>"+script+arr[1];
System.out.println(x);
}
}
the above code when compiled as a java file compiles fine but when used a s a groovy file spits the error :
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
