the below program is to read the time intervals (HH:MM) and to compare system time if the system time between your time intervals print correct time and exit else try again to repeat the same thing. By using StringToknizer class. and i have written like this
import java.io.*;
import java.util.*;
public class Main
{
static int k1,k2,v1,v2;
public static void main(String args[]) throws IOException
{
DataInputStream o=new DataInputStream(System.in);
System.out.println("Enter minimum interval:");
String a=(String)o.readLine();
System.out.println("Enter maximum interval:");
String b=(String)o.readLine();
String c=a+";"+b;
StringTokenizer st=new StringTokenizer(c,":;");
while(st.hasMoreTokens())
{
k1=Integer.parseInt(st.nextToken());
v1=Integer.parseInt(st.nextToken());
k2=Integer.parseInt(st.nextToken());
v2=Integer.parseInt(st.nextToken());
}
Calendar cal=Calendar.getInstance();
int h=cal.get(Calendar.HOUR);
int m=cal.get(Calendar.MINUTE);
if((h>=k1)&&(m>=v1)&&(h<=k2)&&(m<=59))
{
System.out.println("Time: "+h+":"+m);
}
else
{
System.out.println("hi");
}
}
}
but is showing correct for some inputs and wrong for some inputs
and ineed u people suggesstions about this tq
