use like this it will help

String[] subjects = {};
String[] another = {"Physics","Chemistry"};

subjects  = another.clone();

or second option do like this

subjects   = Arrays.copyOf(another , another .length);

this will copy your another array into your subjects array

No, It says This variable cannot be modified – AA Shakil Jan 07 '18 at 18:27
Thanks. I've made this variable final – AA Shakil Jan 07 '18 at 18:32
yes you need to remove final keyword – Sachin Rajput Jan 07 '18 at 18:33
But I am unable to do so. – AA Shakil Jan 07 '18 at 18:33
you just need to write the same code writtern in answer , and if you declare an array as final you can not change its value – Sachin Rajput Jan 07 '18 at 18:34
