public static ClassLoader getClassLoader()
Call this method if you intend to use the thread context ClassLoader in a
scenario where you absolutely need a non-null ClassLoader reference: for
example, for class path resource loading (but not necessarily for
Class.forName
, which accepts a null
ClassLoader
reference as well).

name
- the name of the ClassclassLoader
- the class loader to use (may be null
,
which indicates the default class loader)
ClassNotFoundException
- if the class was not found
LinkageError
- if the class file could not be loadedClass.forName(String, boolean, ClassLoader)
public static Class<?> resolvePrimitiveClassName(String name)
Also supports the JVM's internal class names for primitive arrays. Does
not support the "[]" suffix notation for primitive arrays; this is
only supported by forName(java.lang.String)
.
name
- the name of the potentially primitive class

denote a primitive class or primitive array classpublic static String toShortString(Object obj)
