Java Programs[Important]
- WRITE A JAVA PROGRAM that reads a line of
integers and then displays each integer and the sum of all integers. (use
StringTokenizer class)
-
- Program :
-
- // Using
StringTokenizer class import .lang.*;
import .util.*;
-
- class tokendemo {
public static void main(String args[ ]) { String s="10,20,30,40,50";
int sum=0;
- StringTokenizer
a=new StringTokenizer(s,",",false); System.out.println("integers
are "); while(a.hasMoreTokens()) { int b=Integer.parseInt(a.nextToken());
sum=sum+b; System.out.println(" "+b); } System.out.println("sum
of integers is "+sum); } }
-
- // Alternate
solution using command line arguments
-
- class Arguments {
public static void main(String args[ ]) { int sum=0; int n=args.length;
System.out.println("length is "+n);
-
- int arr[]=new
int[n]; for(int i=0;i<n;i++) arr[i]=Integer.parseInt(args[i]);
- System.out.println("The
enterd values are:"); for(int i=0;i<n;i++) System.out.println(arr[i]);
-
- System.out.println("sum
of enterd integers is:"); for(int i=0;i<n;i++) sum=sum+arr[i];
System.out.println(sum); } }
