characterdemo.java

我自己学习JAVA过程中用键盘敲的代码

package jerryhfb;

public class CharacterDemo {

public static void main(String args[]) {

Character a = new Character('a');

Character a2 = new Character('a');

Character b = new Character('b');

int difference = a.compareTo(b);

if (difference == 0) {

System.out.println("a is equal to b.");

} else if (difference < 0) {

System.out.println("a is less than b.");

} else if (difference > 0) {

System.out.println("a is greater than b.");

}

System.out.println("a is "

+ ((a.equals(a2)) ? "equal" : "not equal")

+ " to a2.");

System.out.println("The character " + a.toString() + " is "

+ (Character.isUpperCase(a.charValue()) ? "upper" : "lower")

+ "case.");

}

}
