To get Class object representing the primitive type by a String

Question

for classes,I can use
classNameString = "java.lang.String"
Class c=Class.forName(classNameString);
to get Class object representing the classNameString.
but to get Class object representing the primitive type ,I have to use something like :
Class c=Integer.TYPE;
is there any way to get Class object representing the primitive type by a String?

Answer 1

not using Class.forName(). you'll just need to key off the String passed to see whether it names a primitive:class ClassUtilities {
   * Gives the <code>Class</code> corresponding to a named class or primitive.
   * @param  name  FQN of a class, or the name of a primitive type
   * @param  loader  a {@link java.lang.ClassLoader ClassLoader}
   * @return  the <code>Class</code> for the name given.  This method
   * converts primitive type names to their particular <code>Class</code>
   * object.  <code>null</code>, the empty string, <code>"null"</code>, and
   * <code>"void"</code> yield {@link java.lang.Void#TYPE Void.TYPE}.  If any
   * classes require loading because of this operation, the given
   * <code>ClassLoader</code> performs the loading.  Such classes are not
   * initialized, however.
   * @throws  ClassNotFoundException  if the name names an unknown class
   * or primitive
   * @see  java.lang.Class#getName
  static Class classForNameOrPrimitive( String name, ClassLoader loader )
    throws ClassNotFoundException {
    if ( name == null || name.equals( "" ) || name.equals( "null" ) || name.equals( "void" ) ) {
      return Void.TYPE;
    if ( name.equals( "boolean" ) )
      return Boolean.TYPE;
    if ( name.equals( "byte" ) )
      return Byte.TYPE;
    if ( name.equals( "char" ) )
      return Character.TYPE;
    if ( name.equals( "double" ) )
      return Double.TYPE;
    if ( name.equals( "float" ) )
      return Float.TYPE;
    if ( name.equals( "int" ) )
      return Integer.TYPE;
    if ( name.equals( "long" ) )
      return Long.TYPE;
    if ( name.equals( "short" ) )
      return Short.TYPE;
    return Class.forName( name, false, loader );
}
