And if both parameters passed are negative. If a negative and a positive number is passed as an argument then the negative result is generated. The arguments are taken in int, double, float and long. This method returns the numeric value of the character, as a nonnegative int value -2 if the character has a numeric value that is not a nonnegative integer -1 if the character has no numeric value. The () function is an inbuilt function in java that returns the minimum of two numbers. Public static int getNumericValue(char ch)Ĭh − the character to be converted Return Value Declarationįollowing is the declaration for () method Alternatively, we can use String.valueOf (char) method. If the char variable contains an int value, we can get the int value by calling Character.getNumericValue (char) method. If we direct assign char variable to int, it will return the ASCII value of a given character. If the character has a numeric value that cannot be represented as a nonnegative integer (for example, a fractional value), then -2 is returned. In Java, we can convert the Char to Int using different approaches. If the character does not have a numeric value, then -1 is returned. The char range lies between 0 to 65,535 (inclusive). It is capable of holding the unsigned 16-bit Unicode characters. It is used to declare the character-type variables and methods. This is independent of the Unicode specification, which does not assign numeric values to these char values. The Java char keyword is a primitive data type.

The letters A-Z in their uppercase ('\u0041' through '\u005A'), lowercase ('\u0061' through '\u007A'), and full width variant ('\uFF21' through '\uFF3A' and '\uFF41' through '\uFF5A') forms have numeric values from 10 through 35. For example, the character '\u216C' (the roman numeral fifty) will return an int with a value of 50.

The (char ch) returns the int value that the specified Unicode character represents.
