Java multiline string

Question

Coming from Perl, I sure am missing the \"here-document\" means of creating a multi-line string in source code:

$string = <<\"EOF\"  # create a three-l         


        

Answer 1

A quite efficient and platform independent solution would be using the system property for line separators and the StringBuilder class to build strings:

String separator = System.getProperty("line.separator");
String[] lines = {"Line 1", "Line 2" /*, ... */};

StringBuilder builder = new StringBuilder(lines[0]);
for (int i = 1; i < lines.length(); i++) {
    builder.append(separator).append(lines[i]);
}
String multiLine = builder.toString();
