Java程序查找学生成绩

编写一个 Java 程序来查找学生成绩并附带示例。为此，我们首先需要计算给定科目的总分和百分比。

Java 程序查找学生成绩示例

此 程序 帮助用户输入五门科目的五个不同的整数值。接下来，它会计算这五门科目的总分和百分比。

为此，我们使用 Java 算术运算符 来执行算术运算。接下来，我们使用 Java Else If 语句 来显示成绩。

import java.util.Scanner;

public class StudentGrade {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int english, chemistry, computers, physics, maths; 
	    float total, Percentage;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter the Five Subjects Marks : ");
		english = sc.nextInt();	
		chemistry = sc.nextInt();	
		computers = sc.nextInt();	
		physics = sc.nextInt();	
		maths = sc.nextInt();	
		
		total = english + chemistry + computers + physics + maths;
	    Percentage = (total / 500) * 100;
	 
	    System.out.println(" Total Marks =  " + total);
	    System.out.println(" Marks Percentage =  " + Percentage);
		
		if(Percentage >= 90)
	    {
			System.out.println("\n Grade A");
		}
		else if(Percentage >= 80)
	    {
			System.out.println("\n Grade B");
		}
		else if(Percentage >= 70)
	    {
			System.out.println("\n Grade C");
		}
		else if(Percentage >= 60)
	    {
			System.out.println("\n Grade D");
		}
		else if(Percentage >= 40)
	    {
			System.out.println("\n Grade E");
		}
		else 
	    {
			System.out.println("\n Fail");
		} 
	}
}

学生成绩示例程序 2

此程序与上述程序相同。但这次，我们创建了一个单独的方法来显示学生成绩。

import java.util.Scanner;

public class StudentGrade1 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int english, chemistry, computers, physics, maths; 
	    
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter the Five Subjects Marks : ");
		english = sc.nextInt();	
		chemistry = sc.nextInt();	
		computers = sc.nextInt();	
		physics = sc.nextInt();	
		maths = sc.nextInt();	
		
		studentGrade(english, chemistry, computers, physics, maths);	
	}	
	public static void studentGrade(int eng, int chem, int com, int phy, int math)
	{
		float total, Percentage;
		
		total = eng + chem + com + phy + math;
	    Percentage = (total / 500) * 100;
	 
	    System.out.println(" Total Marks =  " + total);
	    System.out.println(" Marks Percentage =  " + Percentage);
		
		if(Percentage >= 90)
	    {
			System.out.println("\n Grade A");
		}
		else if(Percentage >= 80)
	    {
			System.out.println("\n Grade B");
		}
		else if(Percentage >= 70)
	    {
			System.out.println("\n Grade C");
		}
		else if(Percentage >= 60)
	    {
			System.out.println("\n Grade D");
		}
		else if(Percentage >= 40)
	    {
			System.out.println("\n Grade E");
		}
		else 
	    {
			System.out.println("\n Fail");
		} 
	}
}

学生成绩输出

 Please Enter the Five Subjects Marks : 80 80 70 85 94
 Total Marks =  409.0
 Marks Percentage =  81.8

 Grade B
