StringgetClassName(String logicalName, String trailingName)
Returns the class name for the given logical name and trailing name. 
if (isBlank(logicalName)) {
    throw new IllegalArgumentException("Argument [logicalName] cannot be null or blank");
String className = logicalName.substring(0, 1).toUpperCase(Locale.ENGLISH) + logicalName.substring(1);

return className;
...
StringgetClassNameRepresentation(String name)
Returns the class name representation of the given name 
String className;
StringBuffer buf = new StringBuffer();
if (name != null && name.length() > 0) {
    String[] tokens = name.split("[^\\w\\d]");
    for (int i = 0; i < tokens.length; i++) {
        String token = tokens[i].trim();
        buf.append(token.substring(0, 1).toUpperCase(Locale.ENGLISH)).append(token.substring(1));
className = buf.toString();
return className;

ArrayList<String> list = new ArrayList<String>();
for (StackTraceElement element : currentStack) {
    list.add(element.getClassName());
return list;
ClassloadClass(Class context, String... names)

ClassloadClass(Class sourceClass, final String className)
load Class 
try {
    ClassLoader loader = sourceClass.getClassLoader();
    if (loader != null) {
        return loader.loadClass(className);
    } else {
        return (Class) Class.forName(className);
} catch (ClassNotFoundException e) {

loadClass(clazz.getName());
ClassloadClass(Class contextClass, String className)
Loads a class using the class loader. 
Class<?> clazz = null;
if (contextClass.getClassLoader() != null) {
    clazz = silentLoadClass(className, contextClass.getClassLoader());
if (clazz == null && Thread.currentThread().getContextClassLoader() != null) {
    clazz = silentLoadClass(className, Thread.currentThread().getContextClassLoader());
