Understanding Conversion Between int and char in Java

Convert Between int and char in Java

In Java, there are two ways to convert between int and char. The first is through the use of the Character class. The Character class provides a static method called toChars() that takes an integer argument and returns a character array containing the corresponding Unicode code points. This can be used to convert an int to the corresponding char value.

The second way to convert between int and char is through the use of the Integer class. The Integer class provides a static method called parseInt() that takes a String argument and returns the corresponding int value. This can be used to convert a char to the corresponding int value.

In both cases, it is important to note that the conversion only works for valid Unicode code points, or characters within the range of a Java char data type (0 through 65535). Attempting to convert an int outside this range will result in an exception being thrown.

It is also important to note that when converting from an int to a char, the value must be cast to a char as int and char are different data types. The same is true when converting from a char to an int.

In conclusion, it is possible to convert between int and char in Java through the use of the Character and Integer classes. However, it is important to remember to cast the value when necessary, and to only use valid Unicode code points.
