对数组的个人理解
package 数组;import java.util.Random;//算二维数组的最大值public class Findsort{public static void main(String args[]){int a[][]=new int[2][5];Random rand=new Random(); for(int i=0;i<2;i++){for(int j=0;j<5;j++){a[i][j]=rand.nextInt(30);System.out.println("a["+i+"]["+j+"]="+a[i][j]);}}int max;Findsort p=new Findsort();max=p.maxv(a);System.out.println("max="+max);} public int maxv(int arr1[][]){int i,j,max;max=arr1[0][0];for(i=0;i<arr1.length;i++)for(j=0;j<arr1[i].length;j++)if(arr1[i][j]>max)max=arr1[i][j];return max;}}
