Alternatively, we can use String.valueOf (char) method. The abbreviation char is used as a reserved keyword in some programming languages, such as C, C++, C#, and Java.

The result of adding Java chars, shorts, or bytes is an int: Java Language Specification on Binary Numeric Promotion: If any of the operands is of a reference type, unboxing conversion (§5.1.8) is performed. A char array is a sequence of characters recorded in memory in a long line of consecutive addresses that can be quickly accessed by using the index of an element within the array. Each Java Program is set of statements and each statement is set of different Java programming lexemes. of data. In this example, we can see how a character in the string is replaced with another one. char c = 'a'; String s = new Character(c).toString(); String t = Character.toString(c); Schaut man jedoch in die Java-Quellen, so stellt man fest, dass beide Methoden intern die statische String-Methode String.valueOf() aufrufen, sodass deren direkter Aufruf das sinnvollste Verfahren ist: The char data type in Java. static char MIN_SURROGATE − This is the minimum value of a Unicode surrogate code unit in the UTF-16 encoding.
