Java – check if string x is equal to any string in string []

If the string entered by the user is equal to any string in the string array, I try to set a Boolean value of true

I improvised and asked this question

String[] cancelWords = {"cancel","nevermind","scratch that"};
boolean valueEqualsCancel = true;
for(String cancelWord : cancelWords) {
  if(!valueEqualsCancel) break;
  valueEqualsCancel =  valueEqualsCancel && value.equals(cancelWord);
}

But valueequalscancel will never be true

Do you have a tip?

Solution

Valueequalscancel will never be true because you won't exit the loop when you find cancelword

To achieve the break statement, you need to set valueequalscancel to false

For example, if you search for "Cancel" after the first loop, the variable valueequalscancel is:

valueEqualsCancel =  valueEqualsCancel && value.equals(cancelWord) = TRUE && TRUE = TRUE;

So you won't break in the second cycle Then evaluate the expression again

valueEqualsCancel =  valueEqualsCancel && value.equals(cancelWord) = TRUE && FALSE = FALSE;

Therefore, in the third loop, you will exit and valueequalscancel is false

You can correct the code by:

String[] cancelWords = {"cancel","scratch that"};
boolean found = false;
for(String cancelWord : cancelWords) {
  found = value.equals(cancelWord);
  if (found) break;
}
