Which device or devices will receive this message? only computer 4 computer 3 and RTR-A computer 4 and RTR-A computer 1, computer 2, computer 4, and RTR-A computer 1, computer 2, computer 3, computer 4, and RTR-A all of the computers and the router 3 . Refer to the exhibit. Hosts A and B, connected to hub HB1, attempt to transmit a frame at the same time but a collision occurs. Which hosts will receive the collision jamming signal? only hosts A and B only hosts A, B, and C only hosts A, B, C, and D only hosts A, B, C, and E 4 . Refer to the exhibit. Router RA receives a packet with a source address of 192.168.1.65 and a destination address of 192.168.1.161...
It sounds like you either need:
ReplyDeleteif (file.exists() && readFileAndCheckForWhatever(file)) {
// File exists and contains the relevant word
} else {
// File doesn't exist, or doesn't contain the relevant word
}
or
if (file.exists()) {
// Code elided: read the file...
if (contents.contains(...)) {
// File exists and contains the relevant word
} else {
// File exists but doesn't contain the relevant word
}
} else {
// File doesn't exist
}
or reversing the logic of the previous one to flatten it
if (!file.exists()) {
// File doesn't exist
} else if (readFileAndCheckForWhatever(file)) {
// File exists and contains the relevant word
} else {
// File exists but doesn't contain the relevant word
}
Unless I am missing something, couldn't you just be using else if?
ReplyDeleteelse if((file.exists())&&(!file.contains(Whatever))) { ... }
File.contains would need to be exchanged for a function that actually checks the file, but you get the idea.
Maybe you mean something like:
ReplyDeleteif(file.exists() && containsLine(file))
{
// do something
}
else
{
// do something else
}
public boolean containsLine(File f)
{
// do the checking here
}
