s=a+aa+aaa+aaaa+aa... The value of a, where a is a number. For example, 2+22+222+2222+22222(at this time a total of 5 Numbers added), several Numbers added with keyboard control.
Program analysis: The key is to calculate the value of each item.
Program design:
import java.io.*;
public class Sumloop {
public static void main(String[] args) throws IOException
{
int s=0;
String output="";
BufferedReader stadin = new BufferedReader(new InputStreamReader(System.in));
System.out.println(" Please enter the a The value of the ");
String input =stadin.readLine();
for(int i =1;i<=Integer.parseInt(input);i++)
{
output+=input;
int a=Integer.parseInt(output);
s+=a;
}
System.out.println(s);
}
}
Another solution:
import java.io.*;
public class Sumloop {
public static void main(String[] args) throws IOException
{
int s=0;
int n;
int t=0;
BufferedReader stadin = new BufferedReader(new InputStreamReader(System.in));
String input = stadin.readLine();
n=Integer.parseInt(input);
for(int i=1;i<=n;i++){
t=t*10+n;
s=s+t;
System.out.println(t);
}
System.out.println(s);
}
}
Java =a+aa+aaa+aaaa+aa... a 5 Numbers add the value of the implementation code, the need for friends can refer to 1.
