[sks9s9]

In this code i am reading a file and than using split() method and than i am sending tkn[] array to a call() function there i want to convert string array into integer

while running this code i am getting some errors
ReadFile1.java:36: incompatible types
found : java.lang.String
required: java.lang.String[]
String str[] = tkn[i];
^
ReadFile1.java:37: non-static method call(java.lang.String[]) cannot be referenced from a static context
call(str) ;
^
ReadFile1.java:57: cannot find symbol
symbol : method charAt(int)
location: class java.lang.String[]
char ch =str.charAt(0);
^
ReadFile1.java:58: cannot find symbol
symbol : method parseInt(char)
location: class java.lang.Integer
int tmp = Integer.parseInt(ch);

Before use, you must initiate the array tkn
