CodePudding user response:

In the int n=sc. NextInt (); After added sc. NextLine ();//remove residues in the input buffer after receive the int data enter a newline character

CodePudding user response:

reference 1st floor qybao response:

in int n=sc. NextInt (); After added sc. NextLine ();//remove the residue after receive the int data in the input buffer carriage return line breaks

I know where the wrong
Should be STR [I]=sc. Next ()
