I think its problem with the listener. 解决方案 RootLayout,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.synth.SynthBorder@5b4b77d,flags=16777673,maximumSize=,minimumSize=,preferredSize=],rootPaneCheckingEnabled=true]Exception in thread "AWT-EventQueue-0" java.lang.NullPointerExceptioninitialTargetFrequency1==50000000initialTargetFrequency2==160000000inputFrequency==40000000initialTargetFrequency150000000initialTargetFrequency2160000000at javaapplication2.EWPLL_AutoCalculateDialog.<init>(EWPLL_AutoCalculateDialog.java:72)at javaapplication2.EWPLL_AutoCalculateDialog8.run(EWPLL_AutoCalculateDialog.java:434)at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311)at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:758)at java.awt.EventQueue.access500(EventQueue.java:97)at java.awt.EventQueue 这篇关于线程中的异常“AWT-eventqueue-0”显示java.lang.NullPointerException的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！ 08-23 11:50
