can anyone please help me how to split the above string as my array

Answer 1

you can use the limit parameter to do this:

The limit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the limit n is greater than zero then the pattern will be applied at most n – 1 times, the array’s length will be no greater than n, and the array’s last entry will contain all input beyond the last matched delimiter. If n is non-positive then the pattern will be applied as many times as possible and the array can have any length. If n is zero then the pattern will be applied as many times as possible, the array can have any length, and trailing empty strings will be discarded.

Example:

String[]
ls_test = "LECT-3A,instr01,Instructor 01,teacher,[e-mail],,,,male,phone,,".split(",",12);

int cont = 0;

for (String ls_pieces : ls_test)
    System.out.println("s["+(cont++)+"]"+ls_pieces);

output:

s[0]LECT-3A
s[1]instr01
s[2]Instructor 01
s[3]teacher
s[4][e-mail]
s[5]
s[6]
s[7]
s[8]male
s[9]phone
s[10]
s[11]
