通过txt文件将对象创建为Java中的数组

LineNumberReader lnr = new LineNumberReader(new FileReader(new File(“File1”)));
lnr.skip(Long.MAX_VALUE);

long length = lnr.getLineNumber();lnr.close();in = new BufferedReader(new FileReader( "data.txt" ));Car[] cars= new Car[length/5];String currentLine;int i=0;for(int i=0;i<length/5;i+=5) {    String name = in.readLine();    String year = in.readLine();    String miles = in.readLine();    String gas = in.readLine();    String color = in.readLine();    cars[i] = new Car(name,year,miles,gas,color);}

您还必须处理异常，将

try catch

结构中的内容包围起来。
