How do I replace all asterisks?

Question

In Java, I want to replace all * characters with \*.

Example: Text: select * from blah

Result: select \\* from blah

public static void main(String[] args) {
    String test = "select * from blah";
    test = test.replaceAll("*", "\\*");
    System.out.println(test);
}

This does not work, nor does adding a escape backslash.

I figured it out

    String test = "select * from blah *asdf";
    test = test.replaceAll("\\*", "\\\\*");
    System.out.println(test);
