    <p>I am trying to read a text file, line-by-line and concatenate the lines to create a single string. But while creating that unified string, <code>0A</code> is being added after each line. The string itself is just one line and I cannot see the <code>0A</code> in normal text/Java editor, but when I open it in an Hex editor, I can see '0A' after each line. I am working on a Linux (Ubuntu) platform.</p> <p>I have tried every possible thing to remove them, specifically <a href="https://stackoverflow.com/questions/6870858/java-how-to-remove-carriage-return-hex-0a-from-string">Java How to remove carriage return (HEX 0A) from String?</a></p> <p>But I am not able to remove them. Any thoughts about how to do this?</p> <p><strong>UPDATE:</strong></p> <pre><code>File workingFolderLocal = new File("src/test/resources/testdata"); String expected = "String1"; MyClass myClass = new MyClass(); myClass.createPopFile(workingFolderLocal); // Read the created file and compare with expected output FileInputStream fin = new FileInputStream(workingFolderLocal + "/output.xyz"); BufferedReader myInput = new BufferedReader(new InputStreamReader(fin)); StringBuilder actual = new StringBuilder(""); String temp = ""; while ((temp = myInput.readLine()) != null) { String newTemp = temp.replaceAll("\r", ""); actual.append(newTemp); } System.out.println("actual: " + actual.toString()); myInput.close(); Assert.assertEquals(expected, actual); </code></pre> <p>Here is the output/error I am getting:</p> <pre><code>actual: String1 FAILED: testCreatPopFile junit.framework.AssertionFailedError: expected:&lt;String1&gt; but was:&lt;String1&gt; at junit.framework.Assert.fail(Assert.java:47) at junit.framework.Assert.failNotEquals(Assert.java:277) at junit.framework.Assert.assertEquals(Assert.java:64) at junit.framework.Assert.assertEquals(Assert.java:71) </code></pre>

    1. COThe recipe in the other question should work. If it doesn't, please provide a small runnable test case demonstrating what exactly is not working for you and in what way.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
