Java 将JDialog转换为Jframe/JPanel
所以我有下面的代码来制作一个测试程序。我使用的代码扩展了JDialog。我想知道是否有办法将其转换为JPanel，因为当我尝试运行代码时，窗口都很小，我似乎无法将完成的按钮移动到“下一步”按钮旁边。如果我想让问题变得随机，人们会怎么做 多谢各位Java 将JDialog转换为Jframe/JPanel,java,swing,jframe,jpanel,jdialog,Java,Swing,Jframe,Jpanel,Jdialog,所以我有下面的代码来制作一个测试程序。我使用的代码扩展了JDialog。我想知道是否有办法将其转换为JPanel，因为当我尝试运行代码时，窗口都很小，我似乎无法将完成的按钮移动到“下一步”按钮旁边。如果我想让问题变得随机，人们会怎么做 多谢各位 import javax.swing.*; import javax.swing.JFrame; import javax.swing.JOptionPane; import java.util.Random; import javax.swing.JR
