Code:

class GFG {
    public static void main (String[] args) 
    {
        Scanner sc=new Scanner(System.in);
        int testcases=sc.nextInt();
        while(testcases--!=0)
        {
            String str=sc.nextLine();
            System.out.println(str);
        }
        //code
    }
}

Answer 1

you have to read a line after int testcases=sc.nextInt(); because reading the Int from scanner is not reading a line Termination chars....

public static void main (String[] args) 
{
    Scanner sc=new Scanner(System.in);
    int testcases=sc.nextInt();
    sc.nextLine();  //<--HERE!
    while(testcases--!=0)
    {
        String str=sc.nextLine();
        System.out.println(str);
    }
