}


i want to stop reading from the user when the user enter "stop" either capital or small 
i don't want to read 50 string how can i do that

Answer 1

Program:

import java.util.Scanner;

public class FindMinLength
{
public static int minLength(String[] array)
{
int minLength = array[0].length();
for (int i = 0; i < array.length; i++)
{
if (array[i].length() < minLength)
minLength = array[i].length();
}
return minLength;
}

public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
int c=0;
String strT="";

//Maximum 50 strings can be acccepted or less as you wanted

for (int i = 1; i<=50; i++)
{
System.out.print("Enter string " + (i) + ": ");
String str = in.nextLine();
if(str.equalsIgnoreCase("STOP"))
{
break;
}
strT=strT+str+"\n";
}
//storing all the strings into string array

String[] strings = strT.split("\n");

System.out.println("Length of smallest length string is " + minLength(strings));
}
}

Output:
