Problem:

Hello,

I was trying to compile my java code but it throws me an error below:

invalid escape sequence (valid ones are \b \t \n \f \r \ \' \\ )" It happened when I was trying to taking input by a Scanner class in my code.

I am really quite new in java. So. it goes beyond my understanding. Could anyone please help me out from here? I must appreciate your help.

Here is the code snippet:

InputReader job = new InputReader
               (new InputReader("\My Documents\job\jobfile.txt"));

Thanks.

Solution:

Well, you need to know the difference between \ and \\ first. In java, | is called an escape character. You need to use the \\ in your file path instead of \

Here you go:

InputReader job = new InputReader
               (new InputReader("\\My Documents\\job\\jobfile.txt"));

Now, this program should work fine without the error you were getting earlier. If you want to know more about escape character, please check this link

Thanks.

Problem: So, guys, I am learning to handle the java scanner class and taking input from the user. Let’s come to my point quickly. I was thinking to write a java program that asking the user for input until they give a valid response. I do have an idea ... condition So, this is my raw flow-chart to write the program. Please correct me if I am wrong anywhere. Any sample program is appreciated.

I saw this code to find difference between diagonal sums of a square matrix. #!/bin/python3 import math import os import random import re import sys def diagonalDifference(arr): d1=0 d2=0 a=n-1 print(arr[1][1]) for i in range(0,n): d1+=arr[i][i] ... ['OUTPUT_PATH'], 'w') with fptr = sys.stdout, the output shows no difference. What then is the difference between functions of these two statements?
