class Soap {
private String s;
Soap() {
System.out.println("Soap()");
s = new String("Constructed");
}
public String toString() { return s; }
}

public class Bath {
private String
// Initializing at point of definition:
s1 = new String("Happy"),
s2 = "Happy",
s3, s4;
Soap castille;
int i;
float toy;
Bath() {
System.out.println("Inside Bath()");
s3 = new String("Joy");
i = 47;
toy = 3.14f;
castille = new Soap();
}
void print() {
// Delayed initialization:
if(s4 == null)
s4 = new String("Joy");
System.out.println("s1 = " + s1);
System.out.println("s2 = " + s2);
System.out.println("s3 = " + s3);
System.out.println("s4 = " + s4);
System.out.println("i = " + i);
System.out.println("toy = " + toy);
System.out.println("castille = " + castille);
}
public static void main(String[] args) {
Bath b = new Bath();
b.print();
}
}
运行结果

Inside Bath()
Soap()
s1 = Happy
s2 = Happy
s3 = Joy
s4 = Joy
i = 47
toy = 3.14
castille = Constructed

我是这样理解的castille = Constructed的结果是由调用class Soap中的String a,但这个变量为私有的为什么public class Bath 还能调用它呢

• 有了Swing为什么还要SWT?
