代碼如下
package inintialization;
import static net.mindview.util.Print.*;
public class Tree {
int height;
Tree() {
print("planting a seedling");
height = 0;
}
Tree(int initialHeight) {
height = initialHeight;
print("Creating new Tree that is " + height + "feet tall");
}
void info() {
print("Three is " + height + "feet tall");
}
void info(String s) {
print(s+":Tree is "+ height +"feet tall");
}
}
package inintialization;
public class Overloading {
public static void main(String[] args) {
// TODO 自動生成的方法存根
for (int i = 0; i < 5; i++) {
Tree t=new Tree(i);
t.info();
t.info("overloaded method");
}
new Tree();
}
}
運行之前不顯示錯誤，點擊運行后報錯資訊如下：
