我有一个方法调用第二个方法,第二个方法将:
第一种方法
public static boolean store(Exception exception, String[][] flags){
return storePrivate(exception, location, flags);
}
第二种方法(并非所有代码都只是相关代码)
private static boolean storePrivate(Exception exception, String dir, String[][] flags){
String flag = "";
for(int i = 0; i >= flags.length; i++){
flag = flag + "" + flags[i][0] + ": " + flags[i][1] + "\n";
}
try {
File directory = new File(dir);
File file = new File(dir + id + ".txt");
if (!directory.exists()) {
directory.mkdirs();
}
file.createNewFile();
FileWriter filewriter = new FileWriter(file.getAbsoluteFile());
BufferedWriter writer = new BufferedWriter(filewriter);
if(flag != ""){
writer.write("Flags by Developer: ");
writer.write(flag);
}
writer.flush();
writer.close();
return true;
} catch (IOException e) {
return false;
}
}
调用第一种方法
public static void main(String[] args) {
try {
test();
} catch (Exception e) {
// TODO Auto-generated catch block
ExceptionAPI.store(e, new String[][]{{"flag1", "Should be part of flag1"}, {"flag2", "this should be flag 2 contence"}});
}
}
public static void test() throws IOException{
throw new IOException();
}
我无法找到为什么这不会起作用。我认为这与第二种方法有关,特别是
if(flag != ""){
writer.write("Flags by Developer: ");
writer.write(flag);
}
谢谢,如果有人可以帮助我。

如果您只想将字符串数组转换为单个字符串,请尝试此操作:
String[] stringTwoD = //... I think this is a 1D array, and Sting[][] is a 2D, anyway
String stringOneD = "";
for (String s : stringTwoD)
stringOneD += s;//add the string with the format you want
顺便说一下,你的循环条件似乎不对,所以你可以把它改成:
for(int i = 0; i < flags.length; i++){
flag += flags[i][0] + ": " + flags[i][1] + "\n";
}
