@Override
public void on Click(View view) {
String text="";
Buffered Reader b r = null;
File Reader f r = null;
try {
f r = new File Reader("assets\\Job\\Job1.txt");
b r = new Buffered Reader(f r);
String line;
in t count=0;
while ((line = b r. read Line()) != null) {
count++;
if(count==19) {
System .out. print ln(line);
}
}
} catch (IO Exception e) {
e. print Stack Trace();
} finally {
try {
if (b r ! = null)
b r . close();
if (f r != null)
f r. close();
} catch (IO Exception ex) {
ex. print Stack Trace();
}
