Java实现带GUI的气泡诗词效果
之前已经为大家介绍过利用Java实现带GUI的气泡诗词特效，本文将为大家介绍另一种方法同样也可以实现气泡诗词的效果。下面是示例代码
import java.awt.*;
import java.awt.event.*;
public class AlgoVisualizer {
private Object data;
private Circle[] circles;
private AlgoFrame frame;
private boolean isAnmiated = true;
String SuShi_Poem = "夜饮东坡醒复醉，归来仿佛三更。" +
"家童鼻息已雷鸣。敲门都不应，倚杖听江声。\n" +
"\n" +
"长恨此身非我有，何时忘却营营。" +
"夜阑风静縠纹平。小舟从此逝，江海寄余生。";
public AlgoVisualizer(int sceneWidth, int sceneHeight, int N){
circles = new Circle[N];
int R = 50;
for(int i = 0; i < N; i++)
{

int y = (int)(Math.random()*(sceneHeight-2*R)) + R;
int vx = (int)(Math.random()*11) - 5;
int vy = (int)(Math.random()*11) - 5;

}

frame.addKeyListener(new AlgoKeyListener());
frame.addMouseListener(new AlgoMouseListener());

"莫听穿林打叶声，何妨吟啸且徐行。竹杖芒鞋轻胜马，谁怕？ 一蓑烟雨任平生。\n" +
