您的错误告诉您第211行出现了导致编译失败的问题。那行是这样的：
jPanel2.setBorder(javax.swing.BorderFactory.createBevelBorder(???, java.awt.Color.red, java.awt.Color.black, java.awt.Color.blue, java.awt.Color.yellow));
你会注意到吗？？？作为第一个参数，这导致了此次编译失败。
从文档中可以看到"？？？"代替应为BevelBorder.LOWERED或BevelBorder.RAISED的type自变量。所以，如果你把上面的行改为，也许它会起作用
jPanel2.setBorder(javax.swing.BorderFactory.createBevelBorder(BevelBorder.LOWERED, java.awt.Color.red, java.awt.Color.black, java.awt.Color.blue, java.awt.Color.yellow));
