reverse.java

基本的数据结构的java代码

import java.io.*;

public class Reverse{
	
	public static void main(String args[]){
				
		int n = 10;
		int[] a = new int[n];
		int[] b = new int[n];
		
		for(int i = 0; i < n; i++){
			a[i] = i+1;
		}
			
		Reverse2(a);
			
		for(int i = 0; i < n; i++){
			System.out.print(a[i] + "  ");
		}
	}

	static void Reverse1(int[] a, int[] b)
	{
		int n = a.length;

		for(int i = 0; i < n; i++)	
			b[i] = a[n - 1 - i];
	}

	static void Reverse2(int[] a)
	{
		int n = a.length;
		int m = n/2;
		int temp;

		for(int i = 0; i < m; i++)
		{
			temp = a[i];
			a[i] = a[n - 1 - i];					
			a[n - 1 - i] = temp;
		}
	}
}
