flower.java

这是我学习JAVA时自己的写的代码

//: Flower.java
// Calling constructors with "this"
public class Flower {
private int petalCount = 0;
private String s = "unll";
Flower(int petals) {
petalCount = petals;
System.out.println("Constructor w/ int arg only, petalCount= "+ petalCount);
}
Flower(String ss) {
System.out.println("Constructor w/ String arg only, s=" + ss);
s = ss;
}
Flower(String s, int petals) {
this(petals);
//! this(s); // Can't call two!
this.s = s; // Another use of "this"
System.out.println("String & int args");
}
Flower() {
this("hi", 47);
System.out.println(
"default constructor (no args)");
}
void print() {
//! this(11); // Not inside non-constructor!
System.out.println("petalCount = " + petalCount + " s = "+ s);
}
public static void main(String[] args) {
Flower x = new Flower();
x.print();
}
