Reading Data from the Text File
I'm trying to read the Data that is present in abc.txt.
The code that I wrote is given below.
import java.io.*;
import java.util.*;
class test
{
publicstaticvoid main(String args[])
{
StringBuffer sb=new StringBuffer();
int rows=0;
int totalvalues=0;
int columns=0;
String s[];
try
{
//scanner is used to scan the textfile
Scanner sc=new Scanner("abc.txt");
//scan each line in the text file
while(sc.hasNextLine())
{
sb.append(sc.nextLine());
rows++;
}
}
catch(Exception e)
{
System.out.println("Exception"+e);
}
s=(sb.toString()).split("");
totalvalues=s.length;
columns=totalvalues/rows;
System.out.println("rows:"+rows+"Columns"+columns);
double normaldata[][]=newdouble[rows+1][columns+1];
int k=0;
System.out.println("S length is:"+s.length);
try{
for(int i = 1; i < rows; i++)
{
for(int j = 1; j < columns; j++)
{
normaldata[i][j] = Double.parseDouble(s[k]);
k++;
}
}
}
catch(Exception e)
{
System.out.println("Exception internally:"+e);
}
for(int i=1;i<=rows;i++)
{
for(int j=1;j<=columns;j++)
{
System.out.print(normaldata[i][j]+"");
}
System.out.println();
}
}
}
