PA Programming Solution Java - 25 January 2020

​Q1. Write a program to print last characters in a string...

Example:

Input:
Hi tcs

Output:
is

​

Solution:

import java.util.Scanner;
public class LastCharOfWord {
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner sc = new Scanner(System.in);
String str = sc.nextLine();
String[] words = str.split(" ");
for (int i = 0; i < words.length; i++) {
System.out.print((words[i].charAt(words[i].length()-1)));
}
sc.close();
}
}
​
Example 1:
Input: welcome home buddY
Output: eeY


Example 2:
Input: Hi how are you ?
Output: iweu?

​

Q2. Take a class name inventory and its 4 object into array and implement a method replenish where it will take array objects and a limit as a parameter and it will display the id along with fillings where filling if greater than 75 it will be critical filling and if it is between 74 and 50 then moderate filling else non-critical filling

​
Input:
1
100
50
50
2
200
60
40
3
150
35
45
4
80
45
40
45
Output:
2 Non-Critical Filling
3 Non-Critical Filling
4 Non-Critical Filling

​

Solution:

sc.nextLine();
int c = sc.nextInt();
sc.nextLine();
int d = sc.nextInt();
sc.nextLine();
in[i] = new Inventory(a, b, c, d);
}
int limit = sc.nextInt();

Critical Filling");

System.out.println(result[i].getInventoryId() + "
Moderate Filling");
}
