Question

Here is the scenario one input

String in = "<ENTER>title=Java-Samples<ENTER>" + 
                        "<ENTER>author=Emiley J<ENTER>" + 
                        "<ENTER>publisher=java-samples.com<ENTER>" + 
                        "<ENTER>copyright=2007<ENTER>" +
                        "<ENTER>cool beans<ENTER>";

processs

    in=in.substring(in.indexOf("<ENTER>")+7,in.lastIndexOf("<ENTER>"));
    String[] mSplitted= in.replaceAll("<ENTER><ENTER>", "<ENTER>").split("<ENTER>");
    String mFinal="";

    for(int i=0;i<mSplitted.length;i++)
    {
       System.out.println("values: "+mSplitted[i]);
       mFinal= mFinal+ mSplitted[i];
    }
    System.out.println(mFinal);

output is

title=Java-Samplesauthor=Emiley Jpublisher=java-samples.comcopyright=2007cool beans

Senario 2

input

        String in = "What is the output of: <ENTER><ENTER>echo 6 % 4;";

processes

    in=in.substring(in.indexOf("<ENTER>")+7,in.lastIndexOf("<ENTER>"));
    String[] mSplitted= in.replaceAll("<ENTER><ENTER>", "<ENTER>").split("<ENTER>");
    String mFinal="";

    for(int i=0;i<mSplitted.length;i++)
    {
      // System.out.println("values: "+mSplitted[i]);
       mFinal= mFinal+ mSplitted[i];
    }
    System.out.println(mFinal);

Output
nothing

I want the output to add a new line when is used

Answer 1

Still not 100% on your question but how about this:

String mFinal = in.replaceAll("<ENTER><ENTER>", "\n").replaceAll("<ENTER>", "");
