本文分享了作者在学习Java基础知识过程中的心得，特别是关于数据结构的学习体会。文中澄清了一些常见的误解，例如LENGTH属性并非方法及Clone方法的正确用法，并通过示例代码展示了如何克隆数组。
:shock: i'm angry because i don't good at the basic java.So,I'm working hard on studying basic java now.First,i bought a book in the culture market yesterday. :oops:
In the following part of this passage,i will write something about Data-Structures. 8)
1,About method LENGTH.
I believe many people think that LENGTH is a method.Oh,that's a shame.
In fact,LENGTH is not a method.You can use LENGTH directly.For example
,<[color=red]Number.length[/color]>.
2,About method CLONE.
You needn't exchange compulsively in JDK5.0.Clone is not copy,the thing you cloned is diffent from the original one.They are independent.For example,Code 1.1.
Code 1.1 :
package array;
class ex1{
public static void main(String[] args) {
int [] a,b;
a=new int[10];
a[5]=0;
b=a.clone();
a[5]=42;
System.out.println(b[5]);
}
}
solution is : 0
