Hi!
I try to exit a function when it gets an IOException
Error, but I don't know how to do that....
public void newfunct() {
try {
} catch (IOException e) {
....do some error handling.....
here should be a command to exit the function
Thanks
Chris MaierYou could have newfunct() throw an IOException and have the calling method do the try{}catch()
i.e.
public void newfunct() throws IOException{
//Your code
//calling method
pubic void caller(){
try{
newfunct();
}catch(IOException){
//handle excption
//continue with rest of code
method2();
method3();
