{
Public static void main(String argv[]) throws IOException

long len;
FileInputStream ins=new FileInputStream(argv[0]);
len=ins.available();
while(len>=1)
{
char ch=(char)ins.read();
System.out.print(ch);
len--;
}
ins.close();
}
}
 

//To copy one file to another file( Can also copy Binary files )
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
class samp
{
Public static void main(String argv[]) throws IOException
{
long len;
FileInputStream ins=new FileInputStream(argv[0]);
FileOutputStream ins=new FileOutputStream(argv[1]);
len=ins.available();
while(len>=1)
{
char ch=(char)ins.read();
outs.write(ch);
len--;
}
outs.close();
ins.close();
}
}

//Executing a file during runtime
import java.lang.System;
import java.lang.Runtime;
