JAVA调用方法，从键盘输入一个float型数组，长度5；…………

package com.bank.cn;

import java.util.Scanner;

public class Test {

	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		float[] x = new float[5];
		float sum=0;
		for(int i=0;i			x[i] = scanner.nextInt();
			sum+=x[i];
		}
		System.out.println("平均数是："+(float)(sum)/5);
		System.out.println("排序前：");
		System.out.println(x.length);
		for(float k:x) {
			System.out.print(k+"\t");
		}
		float[] x1 = new float[5];
		x1 = sort(x);
		System.out.println("\n排序后：");
		for(float i:x1) {
			System.out.print(i+"\t");
		}
	}
	//排序
	private static float[] sort(float[] x) {
		for(int i=0;i			for(int j=i;j				if(x[i]					float temp = x[i];
					x[i]=x[j];
					x[j]=temp;
				}
			}
		}
		return x;
	}
}

结果：
