Class (java-runtime 7.0.128 API)

java.lang.Object
- java.lang.Class<T>

All Implemented Interfaces:

Type
```
public final class Class<T>
extends Object
implements Type
```
Instances of the class Class represent classes and interfaces in a running Java application. Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same element type and number of dimensions. Class has no public constructor. Instead Class objects are constructed automatically by the Java Virtual Machine as classes are loaded. The following example uses a Class object to print the class name of an object: Since: JDK1.0, CLDC 1.0

  - getClassLoader

public ClassLoader getClassLoader()

  - forName

public static Class forName(String className)
                     throws ClassNotFoundException
```
    Deprecated. don't use this method for anything important since class names are obfuscated on the device!
    
    Returns the Class object associated with the class with the given string name. Given the fully-qualified name for a class or interface, this method attempts to locate, load and link the class. For example, the following code fragment returns the runtime Class descriptor for the class named java.lang.Thread: Classt= Class.forName("java.lang.Thread")
    
    Throws:
    
    ClassNotFoundException
  - getName
```
public String getName()
```
    Deprecated. don't use this method for anything important since class names are obfuscated on the device!
    
    Returns the fully-qualified name of the entity (class, interface, array class, primitive type, or void) represented by this Class object, as a String. If this Class object represents a class of arrays, then the internal form of the name consists of the name of the element type in Java signature format, preceded by one or more "[" characters representing the depth of array nesting. Thus: (new Object[3]).getClass().getName() returns "[Ljava.lang.Object;" and: (new int[3][4][5][6][7][8][9]).getClass().getName() returns "[[[[[[[I". The encoding of element type names is as follows: B byte C char D double F float I int J long L class or interface S short Z boolean The class or interface name is given in fully qualified form as shown in the example above.
  - isArray
```
public boolean isArray()
```
    Determines if this Class object represents an array class.
  - isAssignableFrom
```
public boolean isAssignableFrom(Class cls)
```
    Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter. It returns true if so; otherwise it returns false. If this Class object represents a primitive type, this method returns true if the specified Class parameter is exactly this Class object; otherwise it returns false. Specifically, this method tests whether the type represented by the specified Class parameter can be converted to the type represented by this Class object via an identity conversion or via a widening reference conversion. See The Java Language Specification, sections 5.1.1 and 5.1.4 , for details.
  - isInstance
```
public boolean isInstance(Object obj)
```
    Determines if the specified Object is assignment-compatible with the object represented by this Class. This method is the dynamic equivalent of the Java language instanceof operator. The method returns true if the specified Object argument is non-null and can be cast to the reference type represented by this Class object without raising a ClassCastException. It returns false otherwise. Specifically, if this Class object represents a declared class, this method returns true if the specified Object argument is an instance of the represented class (or of any of its subclasses); it returns false otherwise. If this Class object represents an array class, this method returns true if the specified Object argument can be converted to an object of the array class by an identity conversion or by a widening reference conversion; it returns false otherwise. If this Class object represents an interface, this method returns true if the class or any superclass of the specified Object argument implements this interface; it returns false otherwise. If this Class object represents a primitive type, this method returns false.
  - isInterface
```
public boolean isInterface()
```
    Determines if the specified Class object represents an interface type.
  - newInstance
```
public Object newInstance()
                   throws InstantiationException,
                          IllegalAccessException
```
    Creates a new instance of a class.
    
    Throws:
    
    InstantiationException
    
    IllegalAccessException
  - toString
```
public String toString()
```
    Converts the object to a string. The string representation is the string "class" or "interface", followed by a space, and then by the fully qualified name of the class in the format returned by getName. If this Class object represents a primitive type, this method returns the name of the primitive type. If this Class object represents void this method returns "void".
