How to iterate string array for one column in java

Question

I have this code where stringArray contains 1000 words and String[] a contains words which are split into two columns a[0] and a[1].

So, now a[0] contains all words and a[1] contains keys and I want to compare a[0] with another array. How should I do this?

String[] stringArray = swn.mylist.toArray(new String[0]);
String[] a = new String[stringArray.length+1];

for(String words: stringArray) {  
    a = words.split("#");
    System.out.println(a[0]);
}

I guess you are looking for this kind of code:

String[] stringArray = {"Hel#lo","Wel#come","Te#st","I#n","Ja#va"};
String[] a;

for (String words : stringArray) {
    a = words.split("#");
    System.out.println(a[0]);
}

Use equals instead of ==.

For example :

if(word.equals("")){
    //result
}
