如何从readline（）方法打印结果

Question

I'm trying to print out the result from the readline method in a certain format. I also need to add two more if statements, but I'm not sure how to get the code to continue through them if the previous one is true.

public static void main(String[] args) {
    String csvFile = args[0]; //name of our csv file
    BufferedReader br = null;
    String line = "";
    String cvsSplitBy = ",";
    String[] columns = new String[6];
    String columnLine = "";
    float notToBeBelow = 12;

    try {
        br = new BufferedReader(new FileReader(csvFile));
        if ((columnLine  = br.readLine()) != null) {
            columns = columnLine.split(cvsSplitBy);
            while ((line = br.readLine()) != null) {

                // use comma as separator
                String[] routerInfo = line.split(cvsSplitBy);
                if (routerInfo[2].toLowerCase().equals("no")) {
                    float OSVersion = Integer.parseInt(routerInfo[3]);
                    if(OSVersion >= 12) {

                    }
                }

Answer 1

You can do the following:

if (condition) {

} else {
   if (condition2) {}
   else {}

   if (condition3) {}
   else {}
}

You can place an if inside the else of another one.
