You can simply use the + operator or String's concat() method. Or use StringBuilder. You should add an example code to show where you're stuck if you need further information.

Germany and I don't know how to get a job in the USA or UK. I guess the first step would be to apply for a job 🤔 But I think a feed post is better suited for such a survey rishabh tesla.

rishabh tesla Germany. I would try to use the search bar (there are a lot of posts of how to get a job) and if you don't find enough information, post a new question.

rishabh tesla nextLine() reads the full line. Maybe your problem is a wrong way to input. Reading two strings using Scanner.nextLine(): First String [Enter] Second String Wrong: first String [space] second String

rishabh tesla Just test this in the code playground: Scanner scan = new Scanner(System.in); String one = scan.nextLine(); String two = scan.nextLine(); System.out.println(one + " " + two); Write each String in a separate line: Input: Hello, my name is ... Output: Hello, my name is ...

Actually its a question there are two string s and t s is given and t we have to input but its a big line so i have to read the string t and then concatenate it .i have tried the + operator .i think i am stuck in reading the string since string t is a long sentence

For eg string s contains hackerrank and string t contains "is a good place for coding"

And i am unable to use readline method since the imports are default and cannot be changed

Perhaps something like this snippet: String s = "Hackerrank "; Scanner in = new Scanner(System.in); String t = in.nextLine(); System.out.println(s + t);
