Java进阶之梯,成长路线与学习资料,助力突破中间件领域
在Java中,要实现一个有序的数组表示的梯,你可以使用Java内置的集合类,如ArrayList。以下是一个简单的例子,展示了如何创建和操作一个梯形结构:
import java.util.ArrayList;
import java.util.List;
public class Staircase {
private List<Integer> staircase;
public Staircase(int size) {
staircase = new ArrayList<>(size);
for (int i = 0; i < size; i++) {
staircase.add(0);
}
}
public void climb(int steps) {
if (steps < 1 || steps > staircase.size()) {
throw new IllegalArgumentException("Steps must be between 1 and the size of the staircase.");
}
staircase.set(steps - 1, staircase.get(steps - 1) + 1);
}
public int getHeight(int position) {
if (position < 0 || position >= staircase.size()) {
throw new IllegalArgumentException("Position must be non-negative and less than the size of the staircase.");
}
return staircase.get(position);
}
public static void main(String[] args) {
Staircase staircase = new Staircase(10);
for (int i = 0; i < 10; i++) {
staircase.climb(i);
}
for (int i = 0; i < staircase.staircase.size(); i++) {
for (int j = 0; j < staircase.getHeight(i); j++) {
System.out.print("#");
}
System.out.println();
}
}
}
这个例子中,我们定义了一个Staircase类,它有一个ArrayList来表示梯。我们可以通过climb
方法来爬到一个特定的阶梯,通过设置ArrayList中相应位置的值来增加高度。getHeight
方法用于获取特定位置的高度。main
方法中展示了如何使用这个Staircase类来创建一个10阶的梯,并爬到每一阶,然后打印出梯形图案。
