@Builder(builderMethodName = "mandatoryBuilder")
@ToString
public class MyClass {

    private String name;
    private String identifier;

    public String getName() {
        return name;
    }

    public String getIdentifier() {
        return identifier;
    }

    public static MyClassBuilder builder(String identifier) {
        return mandatoryBuilder().identifier(identifier);
    }

}

If you are going to define tooltip for component in ExtJS (especially within version 6.7 and higher as I had chance to work with it) which might be disabled, unfortunately you will not be able to see. This component needs to be enabled that you might see your tooltip. Hopefully there is a way to fix it.

Just enrich your component (button in this case) with pointerEvents: 'all'

var button = {
    xtype: 'button',
    tooltip: 'Your tooltip',
    text: 'Your Text',
    style: {
        pointerEvents: 'all'
    }
};

Inside your .idea folder, change workspace.xml file add below property

<property name="dynamic.classpath" value="true" />

to

<component name="PropertiesComponent">

Have you ever tried to install package available in pypi, but not in official anaconda repository? There is a way to install it using Anaconda terminal.

1. conda skeleton pypi PACKAGE
2. conda build PACKAGE

Last time I was working on migration of some code from Python into Java and I was trying to find a corresponding code in Java for a function called rstrip in Python. So, below you can see a code written in Python and solution written in Java produced of course using Guava.

icb_code.rstrip("0")

CharMatcher trailingZeroMatcher = CharMatcher.is('0');
String trimmedInput = trailingZeroMatcher.trimTrailingFrom(input);

I needed recently to create a case-insensitive map in Java to query it with keys which might be uppercase or lowercase. I thought that it should be somewhere some kind of solution already available for developers. I found a class called CaseInsensitiveMap in Apache Commons Collections package (https://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/map/CaseInsensitiveMap.html) but unfortunately, I found later on that it does not support generics which was needed in my case, that's why I decided to go with a custom solution for that problem which might be found below.

Map<String, String> record = getRecord();

TreeMap<String, String> caseInsensitiveMap = new TreeMap<>getCaseInsensitiveComparator());

caseInsensitiveMap.putAll(record);

protected Comparator<String> getCaseInsensitiveComparator() {
    return Comparator.nullsFirst(String.CASE_INSENSITIVE_ORDER);
}
