我创建了一个非常简单的程序，提示用户输入3个整数，然后确定输入的变量是否创建了一个定义的三角形。为了提高效率，有没有什么提示或建议来简化这个过程？这是我为自己做的练习。我只有6个月的编码，还没有到效率，所以任何帮助或建议将是巨大的。谢谢您。

import java.util.*;

public class Test1 
{
    public static void main(String[] args)
    {
        int[] triangleInput = EnterSides();

        DisplayArray(triangleInput);
        DetermineValidTriangle(triangleInput);
    }

    public static int[] EnterSides()
    {
        Scanner keyboard = new Scanner(System.in);

        int[] triangleInput = new int[3];
        final int numOfSides = 3;

        System.out.println("Please enter " + numOfSides + " integers: ");
        for(int x = 0; x < triangleInput.length; ++x)
        {
            triangleInput[x] = keyboard.nextInt();
        }
        return triangleInput;
    }

    public static void DisplayArray(int[] userInput)
    {
        int[] triangleInput = userInput;

        System.out.print("You have entered: " + Arrays.toString(triangleInput));

        System.out.println();
        System.out.println();
        System.out.println("Side A of triangle is " + triangleInput[0] + ", Side B of triangle is " + 
    triangleInput[1] + ", and Side C of triangle is " + triangleInput[2]);
    }

    public static void DetermineValidTriangle(int[] userInput)
    {
        int[] triangleInput = userInput;
        boolean isTriangle = false;

        if(triangleInput[0] + triangleInput[1] > triangleInput[2])
            if(triangleInput[1] + triangleInput[2] > triangleInput[0])
            {
                 if(triangleInput[0] + triangleInput[2] > triangleInput[1])
                {
                     isTriangle = true;
                }
            }

        System.out.println();
        if(isTriangle)
            System.out.println("Successful triangle has been built!");
        else
            System.out.println("Sorry, Unsuccessful triangle. The requirement for a triangle is A + B 
is greater than C. B + C is greater than A, and A + C is greater than B.");
    }
