Third, the Java SE 8 Platform allows an implementation of class Character to use the Japanese Era code point, U+32FF, from the Unicode Standard version 12.1. Consequently, the behavior of fields and methods of class Character may vary across implementations of the Java SE 8 Platform when ...
IJavaObject IJavaPeerable ISerializable IComparable IConvertible IDisposable Remarks The Character class wraps a value of the primitive type char in an object. An object of class Character contains a single field whose type is char. In addition, this class provides several methods for determining...
* This interface does not refine the general contracts of the {@link* java.lang.Object#equals(java.lang.Object) equals} and {@link* java.lang.Object#hashCode() hashCode} methods. The result of comparing two * objects that implement CharSequence is therefore, in general, * undefined. Each...
Many of the methods of classCharacterare defined in terms of a "Unicode attribute table" that specifies a name for every defined Unicode character as well as other possible attributes, such as a decimal value, an uppercase equivalent, a lowercase equivalent, and/or a titlecase equivalent. Prio...

3. Using Core Java Let’s now see how we can perform the same check if we don’t want to use regular expressions. We’ll take advantage ofCharacterandStringclasses and their methods to check if all required characters are present in ourString: ...
