i want to counting some words in txt file
myfile.txt
ABC,xyzwegwegwe
ABC,12312312312
ABC,sdfsdf3sdfs
how can i count the words"ABC"?
output: "ABC" have: 3
while (myfile.hasNextLine()) {
line = myfile.nextLine();
lines.add(line);
if(xxxxx){ //if have ABC, words++
words++;
}
}
System.out.print("\"ABC\" have: "+words);
I believe what you are trying to do is (and if it only has one copy of "ABC" per line)
if(line.contains("ABC"))
{
words++;
}
String lineToTest = "ABC , sdq2we9ieorwq , EFG"
if(line.contains("ABC"))
{
words++;
}
if(line.contains("EFG"))
{
words++;
}
Notice that this will not check for dupliates!!!
