Java Code that reads a given set of data and decides whether or not it may contain decimal data.

Problem:

Design an algorithm that reads a given set of data and decides whether or not it may contain decimal data.

Solution:

package com.myprograms;

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class DetermineCharacterSet {

String string;
List<Integer> digits = new ArrayList<Integer>();

public static void main(String[] args) {
DetermineCharacterSet characterToIntegerConversion = new DetermineCharacterSet();
characterToIntegerConversion.getTheNUmberAsString();
characterToIntegerConversion.convertToDecimal();
characterToIntegerConversion.printTheResult();

}

public void getTheNUmberAsString(){
Scanner s = new Scanner(System.in);
System.out.println("enter the characters" );
string = s.nextLine();
s.close();
}

public void convertToDecimal(){
for(Character c: string.toCharArray()){
digits.add((int)c);
}
}

public void printTheResult(){
boolean flag = false;
for(Integer n : digits){
if(n >= 48 && n<=57){
flag = true;
}
}
System.out.println("The ascii values are: " + digits);
System.out.println("is given set contains decimals ?? : " + flag);
}
}

Output:

enter the characters
hello
The ascii values are: [104, 101, 108, 108, 111]
is given set contains decimals ?? : false

enter the characters

hell99

The ascii values are: [104, 101, 108, 108, 57, 57]

is given set contains decimals ?? : true
