循环有关问题？

循环问题？急
怎么把数组String []str={"aa","bb","cc","dd","ee","gg","ff","ll","kk","ii"};打印成
  aa bb cc
  dd ee gg
  ff ll kk
  ii
 这样写报越界异常
 for(int i=0;i<=str.length;)
{
for(int j=0;j<3;j++,i++)
{
System.out.print(str[i]);
}
System.out.println();
 
}
  大虾门指点啊！

for(int i=0;i<str.length;)
 {
 for(int j=0;j<3 && i<str.length;j++,i++)
 {
 System.out.print(str[i]);
 }
 System.out.println();
 
}

String []str={"aa","bb","cc","dd","ee","gg","ff","ll","kk","ii"};
for(int i=0;i<str.length;)
{
for(int j=0;j<3;j++,i++)
{
System.out.print(str[i] + " ");
}
System.out.println();

为什么要用双重循环？

Java code

public class Test {    /**     * @param args     */    public static void main(String[] args) {        String []str={"aa","bb","cc","dd","ee","gg","ff","ll","kk","ii"};        for(int i = 0; i < str.length; i++){            if(i > 0 && i % 3 == 0){                System.out.println();            }            System.out.print(str[i] + " ");        }    }}
[解决办法]
Java code
class TestContinue{    public static void main(String args[]){        String []str={"aa","bb","cc","dd","ee","gg","ff","ll","kk","ii"};        int i = 0;        for(String n: str){            System.out.print(n + " ");            i++;            if(i%3 == 0){                System.out.println();                continue;            }        }    }}

我傻了，干嘛用那个continue....
[解决办法]
Java code
class TestContinue{    public static void main(String args[]){        String []str={"aa","bb","cc","dd","ee","gg","ff","ll","kk","ii"};        int i = 0;        for(String n: str)            System.out.print(n + ((++i)%3==0?"\n":"\t"));    }}

楼上方法 精简之上
[解决办法]
Java code
String[] str={"aa","bb","cc","dd","ee","gg","ff","ll","kk","ii"};        for(int i=0;i<str.length;i++){            if(i!=0){                if(i%3==0){                    System.out.println();                }else{                    System.out.print(" ");                }            }                        System.out.print(str[i]);        }
