how to do sorting using java
- by karthikacyr
hi friends,
I have text file with list of alphabets and numbers. I want to do sorting w.r.t this number using java.
My text file looks like this:
a---12347
g---65784
r---675
I read the text file and i split it now. But i dont know how to perform sorting . I am new to java. Please give me a idea.
My output want to be
g---65784
a---12347
r---675
Plese help me. Thanks in advance.
My coding is
String str = "";
BufferedReader br = new BufferedReader(new FileReader("counts.txt"));
while ((str = br.readLine()) != null) {
String[] get = str.split("----");
When i search the internet all suggest in the type of arrays. I tried. But no use.How to inlude the get[1] into array.
int arr[]=new int[50]
arr[i]=get[1];
for(int i=0;i<50000;i++){
for(int j=i+1;j<60000;j++){
if(arr[i]arr[j]){
System.out.println(arr[i]);
}
}
