Determines the character representation for a specific digit in the specified radix.

Usage

From source file:MainClass.java

public static void main(String args[]) {
    System.out.printf("Convert digit to character: %s\n", Character.forDigit(12, 2));

}

From source file:Main.java

public static void main(String[] args) {
    int i1 = 5;//from ww  w  . ja  v a  2 s  . c om
    int i2 = 14;

    char ch1 = Character.forDigit(i1, 10);
    char ch2 = Character.forDigit(i2, 16);

    String str1 = "Char representation of " + i1 + " in radix 10 is " + ch1;
    String str2 = "Char representation of " + i2 + " in radix 16 is " + ch2;

    System.out.println(str1);
