how to check for a Letter in J2ME from a char

Question

how to check for a Letter in J2ME from a char

IN J2SE we can use Character.isLetter(c)

I want to use this : if (Character.isLetter(c) && Character.isUpperCase(c)){} and also else if(Character.isSpace(c))

IN JAVA MOBILE Platform Any way to use it??

Seeing as you can't use Character.isLetter(c) , I would just emulate its functionally. I would do this by treating the character as a "number" by using its ASCII value .

public static boolean isLetter(char c) {
    return (c > 64 && c < 91) || (c > 96 && c < 123);
}

//Not necessary but included anyways
public static boolean isUpperCase(char c) {
    return c > 64 && c < 91;
}

public static boolean isSpace(char c) {
    //Accounts for spaces and other "space-like" characters
    return c == 32 || c == 12 || c == 13 || c == 14;
}
