Java、组合

作者:互联网

编写程序,显示从整数1到7中选择两个数字的所有组合,同时显示所有组合的总数。


package pack2;

public class Combination {

	public static void main(String[] args) {
		combination();
	}

	//组合
	public static void combination() {
		int total = 0;
		
		for (int i = 1; i <= 7; i++) 
			for (int j = i+1; j <= 7; j++, total++) 
				System.out.println(i+" "+j);
		System.out.println("The total number of all combinations is "+total);
	}
}
