 public void runSoftWor(vidio vedio){
 System.out.println("视频长度是 "+vedio.getLength());
 }public void runSoftWor(Voice voice){
     System.out.println("歌曲的名字是 "+voice.getTitle());
 }public boolean runSoftWor(vidio vedio,long maxLength){
    System.out.println("视频长度是 "+vedio.getLength());
     return true;
 }

 }
 定义一个vidio类
 public class vidio {
 private long length;public long getLength() {
     return length;
 }public void setLength(long length) {
     this.length = length;
 }

 }
 定义一个voice类
 public class Voice {
 private String title;public String getTitle() {
     return title;
 }public void setTitle(String title) {
     this.title = title;

 public static void main(String[] args) {    computer com = new computer();
     vidio vedio = new vidio();
     vedio.setLength(999999L);
     com.runSoftWor(vedio);
     Voice voice = new Voice();
