Asha 90.00 A+

COMPLETE JAVA 17 PROGRAM

Complete Java 17 implementation

record Student(String name,int[] marks){double average(){return java.util.Arrays.stream(marks).average().orElse(0);}String grade(){double a=average();return a>=90?"A+":a>=75?"A":a>=60?"B":"C";}}class Main{public static void main(String[] args){Student s=new Student("Asha",new int[]{88,92,90});System.out.printf("%s %.2f %s%n",s.name(),s.average(),s.grade());}}

PROGRAM EXPLANATION

Algorithm and explanation

1. Initialize the deterministic sample values used for build a student grade report in java.
2. Create the required object and apply record and Stream average to its state or behavior.
3. Print the final result and compare it with the documented sample output.

This Java 17 example demonstrates record, Stream average, and Classification through a complete, executable program. The values are intentionally small so students can trace each statement, verify the output, and then modify the example safely in the online compiler.
