在这个简单的程序中，有什么建议或教学可以提高效率吗

Question

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定义的三角形。为了提高效率，有什么技巧或建议可以简明扼要吗？这是我为自己提出的一个练习。我只写了6个月的代码，就效率而言还没有达到，所以任何帮助或建议都会很棒。非常感谢。

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.");
}

}

是的，删除所有内容，然后用以下内容替换：

import java.util.Scanner;
//Do not use "import java.util.*;" this will import the entire library in java.util
public class Test1
{
public static void main()
{
Scanner keyboard = new Scanner(System.in);
int trianglePoint1X = keyboard.nextInt();
int trianglePoint1Y = keyboard.nextInt();
int trianglePoint2X = keyboard.nextInt();
int trianglePoint2Y = keyboard.nextInt();
int trianglePoint3X = keyboard.nextInt();
int trianglePoint3Y = keyboard.nextInt();
//No Arrays, they are unneccessary
//No Checks, the triangle does not need to be checked to confirm it's a triangle, the user should have freedom to set points
//Triangle should have it's corners stored in memory instead of it's sides
}
public void drawTriangle()
{
//connect triangle point 1 with 2
//connect triangle point 2 with 3
//connect triangle point 3 with 1   
}
}
