Character constants in Java Part- I

Some of the constants of the Character class in Java.

1. Character.BYTES

Syntax:

int java.lang.Character.BYTES

The number of bytes is used to represent a char value in unsigned binary form (i.e 2).

Approach:

Java

public class CharacterBYTES {
    public static void main(String[] args) {

        System.out.println(Character.BYTES);
    }
}

Output:

2

2. Character.MAX_CODE_POINT

Syntax:

int java.lang.Character.MAX_CODE_POINT

The maximum value of a Unicode code point, constant U+10FFFF (i.e 1114111)

Approach:

Java

public class CharacterMaxCodePoint {
    public static void main(String[] args) {

        System.out.println(Character.MAX_CODE_POINT);
    }
}

Output:

1114111

3. Character.MAX_HIGH_SURROGATE

Syntax:

char java.lang.Character.MAX_HIGH_SURROGATE : '�'

The maximum value of a Unicode high-surrogate code units in the UTF-16 encoding, constant '\u005CuDBFF'.A high-surrogate is also known as a leading surrogate. 

Approach:

Java

public class CharacterMaxHighSurrogate {
    public static void main(String[] args) {

        System.out.println(Character.MAX_HIGH_SURROGATE);
    }
}

Output:

?

4. Character.MAX_LOW_SURROGATE

Syntax:

char java.lang.Character.MAX_LOW_SURROGATE : '�'

The maximum value of a Unicode low-surrogate code unit in the UTF-16 encoding, constant '\u005CuDFFF'.A low-surrogate is also known as a trailing-surrogate.

Approach:

Java

public class CharacterMaxLowSurrogate {
    public static void main(String[] args) {

        System.out.println(Character.MAX_LOW_SURROGATE);
    }
}

Output:

?

5. Character.MAX_RADIX

Syntax:

int java.lang.Character.MAX_RADIX : 36

The maximum radix is available for conversion to and from strings. The constant value of this field is the largest value permitted for the radix argument in radix-conversion methods such as the digit method, the forDigit method, and the toString method of class Integer.

Approach:

Java

public class CharacterMaxRadix {
    public static void main(String[] args) {

        System.out.println(Character.MAX_RADIX);
    }
}

Output:

36

6. Character.MAX_SURROGATE

Syntax:

char java.lang.Character.MAX_SURROGATE: '�' 

The maximum value of a Unicode surrogate code unit in theUTF-16 encoding, constant '\u005CuDFFF'.

Approach:

Java

public class CharacterMaxSurrogate {
    public static void main(String[] args) {

        System.out.println(Character.MAX_SURROGATE);
    }
}

Output:

?

7. Character.LINE_SEPARATOR

Syntax:

byte java.lang.Character.LINE_SEPARATOR: 13

General category "Zl" in the Unicode specification. 

Approach

Java

public class CharacterConstants7 {
    public static void main(String[] args) {

        System.out.println(Character.LINE_SEPARATOR);
    }
}

Output:

13

8. Character.LOWERCASE_LETTER

Syntax:

byte java.lang.Character.LOWERCASE_LETTER: 2

General category "Ll" in the Unicode specification.

Approach

Java

public class CharacterConstants7 {
    public static void main(String[] args) {
        System.out.println(Character.LOWERCASE_LETTER);

    }
}

Output:

2
