When I run this code. I have some problem. problem sentence is "java.util.Scanner[delimiters=\p{javaWhitespace}+][position=2][match valid=true][need input=false][source closed=false][skipped=false][group separator=\,][decimal separator=.][positive prefix=][negative prefix=\Q-\E][positive suffix=][negative suffix=][NaN string=\Q?\E][infinity string=\Q∞\E]"
Please somebody help us .....!!!!!!
