Question

I have a string which has delimiter in it. I want to know the best way to replace the delimiter with a new line. I have had various issues with using the String Tokenizer the main problem being NoSuchElementException. Basically my approach thus far is to retrieve data from a database Once this has been achieved I store each of the records in a string String question = c.getString(1);
Here is the string tokenizer StringTokenizer st = new StringTokenizer(question,"<ENTER>"); I loop through the tokens using a while loop

 while (st.hasMoreTokens()) {
                        System.err.println(st.nextToken());
                       // quest.setText(String.valueOf(st.nextToken("<ENTER>")));

            }

Working example in code

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

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

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

xml code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/quest"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:singleLine="false"
        android:text="TextView" />


    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="0.08"
        android:text="@string/hello" />

    <Button
        android:id="@+id/Next"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</LinearLayout>

Answer 1

can’t you use split() of String.

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

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];
}
quest.setText(mFinal);
