Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index 2 out of bounds for length 2
at Test.main(Test.java:20)
What I have tried:
String
path1 =
"
C:\\Users\\savac\\OneDrive\\Desktop\\Proiect\\RStudenti.csv"
;
String
line1 =
"
"
;
Student[] studenti=new Student[
2
];
try
{
int
i=0;
BufferedReader br =
new
BufferedReader(
new
FileReader(path1));
while
((line1 = br.readLine())!=null) {
String
[] values = line1.split(
"
,"
);
studenti[i]=new Student(values[
0
],values[
1
],Integer.parseInt(values[
2
]));
}
catch
(FileNotFoundException e){
e.printStackTrace();
}
catch
(IOException e){
e.printStackTrace();
studenti[i]=
new
Student(values[0],values[1],Integer.parseInt(values[2]));
Suspecting, mostly this line. You must have passed only 2 values comman separated as input leading to an error when you tried to access values[2]
Couple of suggestions:
1. Make sure to check for length before accessing the index
2. Use IDE Debugger and it would be easy to figure whats wrong. You will learn more when you do.

Very simple !
You try to use the third value of an array which contain only 2 values.
You need to check the size of the array.
Do something like:
while
((line1 = br.readLine())!=null) {
String
[] values = line1.split(
"
,"
);
if
(size of values >=
3
) {
studenti[i]=new Student(values[
0
],values[
1
],Integer.parseInt(values[
2
]));
}
else
{
I let you search for exact syntax.
Read the question carefully.
Understand that English isn't everyone's first language so be lenient of bad
