读取文件并将其存储在数组中,然后在有}的地方将文件拆分, [英] Reading a file and storing it in an array, then splitting up the file everywhere there is a },
问题描述
我想读取一个文件并将其存储在数组中,然后在有}的位置将其拆分,以便数组中的每个项目都包含拆分后的字符串.这就是我的意思,
I want to Read a file and store it in an array, then split up the array everywhere there is a }, so that each item in the array contains the string split up. Here is what I mean,
我的文件包含以下内容:
My file contains stuff like this:
[
{
"sample1": {
"color": "red",
"date": "2011,
"name": "george"
}
},
{
"sample2": {
"color": "red",
"date": "2012",
"name": "phil"
}
},
我想阅读此文件,例如在数组中具有oth元素来表示
I want to read this file, have have for example the oth element in the array to represent
{
"sample1": {
"color": "red",
"date": "2011,
"name": "george"
}
},
并用第一个元素表示
{
"sample2": {
"color": "red",
"date": "2012",
"name": "phil"
}
},
现在我不太确定该怎么做,我不知道数组的大小,也不确定如何访问数组的每个元素,到目前为止,我已经开始了
Now I am not too sure how to do this, I don't know what the size of my array will be and I am not sure how I will access each element of my array, I have started off with this so far
String str;
char[] getArray;
FileReader fr = new FileReader("/sampleProject");
BufferedReader br = new BufferedReader(fr);
br.readLine();
while ((str = br.readLine()) != null) {
str.toCharArray();
str.split("},");
}
System.out.println("Here it is" + str);
br.close();
}
推荐答案
如果您不知道数组的大小,则可以使用ArrayList.
str.toCharArray();
和str.split("},")};
可能未达到预期的效果,因为您从未分配返回的值.
If you don't know, what size an array is you can use ArrayList.
str.toCharArray();
and str.split("},")};
probably don't do what you expect, since you never asign the returned value.
我没有对此进行测试,但是也许它可以满足您的需求:
I didn't test this, but maybe it does what you need:
String str;
char[] getArray;
FileReader fr = new FileReader("/sampleProject");
BufferedReader br = new BufferedReader(fr);
br.readLine();
ArrayList<String> result = new ArrayList<>();
while ((str = br.readLine()) != null) {
String[] array = str.split("},");
for(int i = 0; i< array.length;i++) {
result.add(array[i]);
}
}
System.out.println("Here it is" + str);
br.close();
