The list of methods to do Object Type Case are organized into topic(s).

Method

Tcast(Class type, Object key, Object value)
cast 
if (value == null) {
    return null;
if (!type.isAssignableFrom(value.getClass())) {
    throw new Exception("Value has invalid type" + (key == null ? "" : " for key: " + key)
            + " -- expected '" + type.getName() + "', got: " + value.getClass().getName());
return (T) value;
...
Tcast(Class type, Object obj)
Cast an object type to the specified type. 
return (type.isInstance(obj)) ? type.cast(obj) : null;
int[]cast(double[] arr)
cast double[] to int[] 
int[] carr = new int[arr.length];
for (int i = 0; i < arr.length; i++) {
    carr[i] = (int) arr[i];
return carr;
Classcast(final Class clazz)
Casts a class to a required type 
return (Class<T>) clazz;
Rcast(final Number number, final Class returnType)
Casts the number to the provided return type. 
if ((number == null) || (returnType == null)) {
    return null;
if (returnType == Double.class) {
    final Double value = number.doubleValue();
    return returnType.cast(value);
} else if (returnType == Float.class) {
    final Float value = number.floatValue();
...
Tcast(final Object o)
Utility method to perform generic casts without dealing with Unchecked cast warnings (or having to apply SuppressWarnings("unchecked") annotations). 
return (T) o;
Tcast(final Object obj, final Class type)
Casts the given object to the specified type, or null if the types are incompatible. 
if (!canCast(obj, type))
    return null;
@SuppressWarnings("unchecked")
final T result = (T) obj;
return result;
Tcast(final Object object)
Auto cast an object. 
return (T) object;
Tcast(final Object original)
Casting in the way that it is not a problem for findbugs yet it can throw a classcast exception. 
@SuppressWarnings("unchecked")
T result = (T) original;
return result;
shortcast(int value)
cast 
return value > Short.MAX_VALUE ? Short.MAX_VALUE
        : value < Short.MIN_VALUE ? Short.MIN_VALUE : (short) value;
