Java 程序用于检查三角形是等边、等腰还是不等边

编写一个 Java 程序，用示例检查三角形是等边、等腰还是不等边。如果三角形的所有边都相等，则为等边三角形。如果任何两条边相等，则为等腰三角形，否则为不等边三角形。此 Java 示例允许输入三角形的三条边。接下来，我们使用 else if 来检查所有边是否相等或任意两条边是否相等。根据条件结果，我们打印等边或等腰，如果都不满足，则为不等边。

package Area;

import java.util.Scanner;

public class EquiIsoScalene1 {
	private static Scanner sc;

	public static void main(String[] args) {
		
		double side1, side2, side3;
		sc = new Scanner(System.in);	
		
		System.out.println("Please Enter Three sides of Triangle ");
		side1 = sc.nextDouble();
		side2 = sc.nextDouble();
		side3 = sc.nextDouble();
		
		if(side1 == side2 && side2 == side3) 
		{
			System.out.println("It is an Equilateral Triangle");
		}	
		else if(side1 == side2 || side2 == side3 || side1 == side3) 
		{
			System.out.println("It is an Isosceles Triangle");
		} 
		else 
		{
			System.out.println("It is a Scalene Triangle");
		}
	}
}

It is a Scalene Triangle

在此 Java 程序中，我们声明了 checkTriangle 函数，该函数接受三角形的边并检查三角形是等边、等腰还是不等边。

package Area;

import java.util.Scanner;

public class EquiIsoScalene2 {
	private static Scanner sc;

	public static void main(String[] args) {
		double side1, side2, side3;
		sc = new Scanner(System.in);
		
		System.out.println("Please Enter Three sides of Triangle ");
		side1 = sc.nextDouble();
		side2 = sc.nextDouble();
		side3 = sc.nextDouble();
		
		checkTriangle(side1, side2, side3);
	}
	
	public static void checkTriangle(double side1, double side2, double side3)
	{
		if(side1 == side2 && side2 == side3) {
			System.out.println("It is an Equilateral Triangle");
		}
		else if(side1 == side2 || side2 == side3 || side1 == side3) {
			System.out.println("It is an Isosceles Triangle");
		}
		else {
			System.out.println("It is a Scalene Triangle");
		}
	}
}
