Question

Grade of Steel (10 Points) (JAVA)
A certain grade of steel is graded according to the following conditions:
a) Hardness (integer) must be greater than 50
b) Carbon content (float) must be less than 0.7
c) Tensile strength (integer) must be greater than 5600
The grades are as follows:
• Grade is 10 if all three conditions are met
• Grade is 9 if conditions a) and b) are met
• Grade is 8 if conditions b) and c) are met
• Grade is 7 if conditions a) and c) are met
• Grade is 6 if only one condition is met
• Grade is 5 if none of the conditions are met
Write a program, which will require the user to give values of hardness,
carbon content and tensile strength of the steel under consideration and
output the grade of the steel.
Below are sample runs (the values highlighted in red are user inputs).
1. Length
2. Mass
3. Temperature
Welcome to Unit Converter! Please choose from the menu
(1-3): 1
1. Foot
2. Inch
Please choose a unit to convert from (1-2): 2
1. Foot
2. Inch
Please choose a unit to convert to (1-2): 1
Please enter the value: 100
100 Inch = 8.333333333333334 Foot
Enter hardness: 60
Enter carbon content: 0.2
Enter tensile strength: 6000
Grade of steel is 10
Enter hardness: 40
Enter carbon content: 1.2
Enter tensile strength: 5000
Grade of steel is 5
Enter hardness: 75
Enter carbon content: 1.5
Enter tensile strength: 4000
Grade of steel is 6

Program:-

package demo;

import java.util.Scanner;

public class DemoTranslation {
   public static void main(String[] args) {
       {
           int n;
           int[] a = new int[100], c = new int[100];
           float[] b = new float[100];
           n = STDIN_SCANNER.nextInt();
           for(int i = 0; i < n; i++) {
               a[i] = STDIN_SCANNER.nextInt();
               b[i] = STDIN_SCANNER.nextFloat();
               c[i] = STDIN_SCANNER.nextInt();
           }
           for(int i = 0; i < n; i++) {
               if(a[i] > 50 && b[i] < 0.7 && c[i] > 5_600) {
                   System.out.println("10");
               } else if(a[i] > 50 && b[i] < 0.7 && c[i] < 5_600) {
                   System.out.println("9");
               } else if(a[i] < 50 && b[i] < 0.7 && c[i] > 5_600) {
                   System.out.println("8");
               } else if(a[i] > 50 && b[i] > 0.7 && c[i] > 5_600) {
                   System.out.println("7");
               } else if(a[i] > 50 || b[i] < 0.7 || c[i] > 5_600) {
                   System.out.println("6");
               } else if(a[i] < 50 && b[i] > 0.7 && c[i] < 5_600) {
                   System.out.println("5");
               }
           }
           return;
       }
   }

   public final static Scanner STDIN_SCANNER = new Scanner(System.in);
