an if statement that searches a string

in Programming Questions • 2 years ago

This is probably really simple, but is there a way to search a string for a word in an if statement?

EDIT:

I got this working. Is there a way to search for multiple words?

if(entry.getTitle().contains("green latern")){
chooser=0;
}
else{
chooser=1;
}

You could use && and || in the if statement to add more things.

if (entry.getTitle().contains("green latern") || entry.getTitle().contains("wolverine")) {
chooser = 0;
} else{
chooser = 1;
}

thank you, is there a short hand such as

if(entry contains ("this" or "that"or "those"))

{

do stuff

}

I have quite a few strings to enter it would be a pain to have to make them all separate.

Well, in that case perhaps a function is more practical. Then you can just run the whole list of names through it.

String[] names;
void keyPressed() {
for (int i=0; i<names.length; i++) {
checkName(names[i]);
}
}
void checkName(String s) {
if (entry.getTitle().contains(s)) {
chooser = 0;
println("entry contains: " + s);
} else {
chooser = 1;
}
}

Alternative:

void setup()
{
println(contains("One for the money, two for the show", "one", "two", "three"));
println(contains("Now, for something completely different", "one", "two", "three"));
}
boolean contains(String haystack, String... needles)
{
for (String needle : needles)
{
if (haystack.contains(needle))
{
return true;
}
}
return false;
}
