Java程序查找三角形的角度

编写一个Java程序来查找三角形的角度，并附有示例。此Java示例允许输入三角形的另外两个角。众所周知，三角形的三个角之和等于180度。因此，从180中减去给定的两个角即可得到三角形的第三个角。

package Area;

import java.util.Scanner;

public class AngleOfTriangle1 {
	private static Scanner sc;

	public static void main(String[] args) {
		int ang1, ang2, ang3; 
		sc = new Scanner(System.in);
		
		System.out.println("Enter two angles of a Triangle =  ");
		ang1 = sc.nextInt();
		ang2 = sc.nextInt();
		
		ang3 = 180 - (ang1 + ang2);

		System.out.format("The Third Angle of a Triangle = %d",ang3);
	}
}

Enter two angles of a Triangle =  
60
45
The Third Angle of a Triangle = 75

在此程序中，我们声明了一个TriangleAngle函数，该函数返回三角形的剩余角或第三个角。

package Area;

import java.util.Scanner;

public class AngleOfTriangle2 {
	private static Scanner sc;

	public static void main(String[] args) {
		int ang1, ang2, ang3; 
		sc = new Scanner(System.in);
		
		System.out.println("Enter two angles of a Triangle =  ");
		ang1 = sc.nextInt();
		ang2 = sc.nextInt();
		
		ang3 = TriangleAngle(ang1, ang2);

		System.out.format("The Third Angle of a Triangle = %d",ang3);
	}
	
	public static int TriangleAngle(int ang1, int ang2) {
		return 180 - (ang1 + ang2);
	}
}
