How to make replaceAll working in java?

I've tried different way but not working yet.

public String SuEscapeHTML(String text){
    text=text.replaceAll("/&/g", "&");
    // and how to deal with the double quote? text=text.replaceAll("/"/g", """);
    text=text.replaceAll("/'/g", "'");
    text=text.replaceAll("/</g", "&lt;");
    text=text.replaceAll("/>/g", "&gt;");
    text=text.replaceAll("/\\/g", "&#92;");
    System.out.println(text);
    return text;
}

nothing change by using this function.

So How to make it working?

The syntax of regex you are using is of JavaScript. This is how you will do it in Java

String text = "&>\"<\\'"; //You need to escape " in text also

System.out.println(text.replaceAll("&", "&amp;")); 
System.out.println(text.replaceAll("\"", "&quot;")); //For quotes
System.out.println(text.replaceAll("'", "&apos;"));
System.out.println(text.replaceAll("<", "&lt;"));
System.out.println(text.replaceAll(">", "&gt;"));
System.out.println(text.replaceAll("\\\\", "&#92;"));
