Ciao a tutti!! ho una stringa, recuperata da un DB fatta così:
devo trasformarla in una matrice double[][] fatta cosìcodice:1;2;;|;3;;|;;4;|;;;5|;;;6|;;5;
ho creato una funzione così fattacodice:1 2 0 0 0 3 0 0 0 0 4 0 0 0 0 5 0 0 0 6 0 0 5 0
Ma non funziona, mi ritorna una ArrayIndexOutOfBoundsException,codice:public static double[][] conversione2D(String a,String carattere,String car){ String array[] = a.split(car); int misura = array.length; System.out.println("La Z:" + misura); System.out.println("Il carattere:" + carattere); int misura2 =array[0].split(carattere).length; System.out.println("La X:" + misura2); double out[][] = new double[misura][misura2]; for(int i=0;i<misura;i++){ String x[] = array[i].split(carattere); System.out.println("La lunghezza:" + x.length); for(int j=0;j<x.length;j++){ if(!x[j].isEmpty()){ out[i][j] = Double.parseDouble(x[j]); } else out[i][j]=0; } }
Per favore aiutatemi!!codice:Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 2 at wave.simulator.tabelle.DB.conversione2D(DB.java:191) at wave.simulator.Inter_importazione.importa(Inter_importazione.java:182) at wave.simulator.Inter_importazione.save(Inter_importazione.java:104) at wave.simulator.Inter_importazione.access$000(Inter_importazione.java:22) at wave.simulator.Inter_importazione$1.actionPerformed(Inter_importazione.java:72) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2341) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:402) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:252) at java.awt.Component.processMouseEvent(Component.java:6504) at javax.swing.JComponent.processMouseEvent(JComponent.java:3321) at java.awt.Component.processEvent(Component.java:6269) at java.awt.Container.processEvent(Container.java:2229) at java.awt.Component.dispatchEventImpl(Component.java:4860) at java.awt.Container.dispatchEventImpl(Container.java:2287) at java.awt.Component.dispatchEvent(Component.java:4686) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4832) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4492) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4422) at java.awt.Container.dispatchEventImpl(Container.java:2273) at java.awt.Window.dispatchEventImpl(Window.java:2713) at java.awt.Component.dispatchEvent(Component.java:4686) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:707) at java.awt.EventQueue.access$000(EventQueue.java:101) at java.awt.EventQueue$3.run(EventQueue.java:666) at java.awt.EventQueue$3.run(EventQueue.java:664) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:87) at java.awt.EventQueue$4.run(EventQueue.java:680) at java.awt.EventQueue$4.run(EventQueue.java:678) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:677) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:211) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:128) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:117) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:113) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:105) at java.awt.EventDispatchThread.run(EventDispatchThread.java:90)
