Getting No Output. Can anyone say why?

Question

class Myclass {
public static void main(String[] args) {
String [] arr = {"a" , "b" , "c"};
String a="abc";
String [] part = a.split("");
for(int i=0;i<part.length;i++) {
if(arr[i]==part[i]) {
System.out.print(part[i]);
}
}
}
}

Answer 1

Because if(arr[i] == part[i]) is false on every line. Change it to if(arr[i].equals(part[i])) and it should work.

Always use equals() method to compare Strings (and other objects too). Because (arr[i] == part[i]) checks if it is exactly the same object

Answer 2

You are using wrong comparator == is for object reference. Use equals method to compare content arr[i].equals(part[i])
