第一个类 - 即NewPlayer类

第二类,即继续课
public class Continue extends javax.swing.JDialog {

private int usernumb;
private boolean check;
private int uNomba;
private String cdirectory;
private String cbdir;
private String ctabname;
private String ctarget;
private List list;
/**
* Creates new form Continue
*/
public Continue(java.awt.Frame parent, boolean modal) {
super(parent, modal);
initComponents();
}
public Continue(int CUNOMBA, int COUNT, boolean CHECK, List NLIST){
this.uNomba = CUNOMBA; //user number obtained from NewSound class
this.count=COUNT;
this.check=CHECK;
this.list=NLIST;
}
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
new NewPlayer().setVisible(false);//closePrj();
count++;
check=true;
new NewPlayer(uNomba, count, check, list).load();
System.out.println("Continue: UserNumber: "+uNumb+", Count: "+count+", Check: "+check+", nList"+lst);
this.setVisible(false);
}
谢谢sgroh。这是我刚刚添加的内容:我创建了以下内容
在NewPlayer类中:
继续ct = new继续(新的NewPlayer(uNomba,i,moveon,numlist));
在继续课堂上, 私人NewPlayer np;
public Continue (NewPlayer npy){
this.npy=np;
}
回顾一下,我遇到的主要问题是我无法访问从Continue类传递给NewPlayer类的值。我在Continue类中测试了以下构造函数中的值,但在Continue类中没有测试其他任何地方。
public Continue(int CUNOMBA, int COUNT, boolean CHECK, List NLIST){
this.uNomba = CUNOMBA; //user number obtained from NewSound class
this.count=COUNT;
this.check=CHECK;
this.nlist=NLIST;
System.out.println("Continue-constructor - uNomba: "+uNomba+", nList: "+list); //works fine! but not outside this constructor.
}
答案 0 :(得分:0)
这段代码甚至可以编译,你没有构造函数默认值(没有字段)。 这样:
public Continue(java.awt.Frame parent, boolean modal) {
和这:
public Continue(int CUNOMBA, int COUNT, boolean CHECK, List NLIST){
这个小编译:
Continue ctn = new Continue();
答案 1 :(得分:0)
您必须使用正确的构造函数创建Continue对象,或者创建Default构造函数。
您还需要在System.out.println中打印不存在的变量uNumb。
