下面是一个示例代码,演示如何使用StringBuilder来处理超长字符串: publicclassMain{publicstaticvoidmain(String[]args){StringlongString="This is a very long string that exceeds the maximum length of a normal String in Java.";StringBuildersb=newStringBuilder();sb.append(longString);System.out.println(sb....
回到length方法,我们看到length的值是通过是value获得的,而value在JDK8中是以char数组实现的: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 publicfinalclassStringimplementsjava.io.Serializable,Comparable<String>,CharSequence{/** The value is used for character storage. */privatefinal char value[];/...
*code units in the string *@return the length of the sequence of characters represented by this object */ public int length(){ return value.length; } 1. 2. 3. 4. 5. 6. 7. 8. 9. 我们看到上面的代码返回值类型是int类型,java中定义数组是可以给数组指定长度的,不指定的话是根据数组元素来...
In practical terms, you should be able to create a String with a length of Integer.MAX_VALUE or half of your maximum heap size, whichever is smaller. However, it's worth noting that creating a String of such extreme size might have significant memory implications and may not be practical ...

Given a string s, find the longest palindromic substring in s. You may assume that the maximum length of s is 1000. 翻译: 给定一个字符串s,找出s中最长的回文子串。你可以假设s的最大长度是1000。 什么叫回文子串? 就是字符串中,满足能正读反读都一样的子串,就是回文子串。如下所示 ...
