java编程问题（找最大数）

错误是：1.数组长度只有5，但是需要给它赋值6个值2.intk=1;m[k-1]=j;k--;知道你这是什么意思吗？值是否为数组元素赋值？3、最大值法如果输入1、2、3、4、5、6就很有问题。
最大的数是多少？1-6之间最大的数是1吗？正确答案是importjavax.swing.JOptionPane;/****@authorSong*/publicclassMain{/***@paramargsthecommandlineararguments*/publicstaticvoidmain(String[]args){int[]m=newint[6];for(int=0;i<=5;i++){StringnString=JOptionPane.showInputDialog("enteranumber");intj=Integer.parseInt(nString);m[i]=j;}intx=max(m);JOptionPane.showMessageDialog(null,"theh3estoneis"+x);//TODOcodeapplicationlogichere}publicstaticintmax(int[]a){ints=a[0];for(int=1;is){s=a[i];}}返回;}}
