char ch = 'a'; ch = Character.toUpperCase(ch); System.out.println(ch); // prints 'A'
char ch = '7'; boolean isDigit = Character.isDigit(ch); System.out.println(isDigit); // prints true
char ch = '5'; int intValue = Character.getNumericValue(ch); System.out.println(intValue); // prints 5This example uses the `getNumericValue()` method of the Character class to convert a numeric character to its corresponding integer value. Overall, the java Character class provides a range of methods to manipulate and convert characters. It is a part of the java.lang package and does not require any additional library imports.
