Improve Java application performance with CRaC support 1. Overview Usually, when we talk aboutconverting anintnumber to achar,we’ll perform the conversion based on the targetchar‘sASCII code. However, in this tutorial, we’ll look at a different scenario of converting anintvalue to a letter...
equals equalsIngoreCase 比较大小 public int compareTo(String anotherString);比较两个字符串的大小关系 负数:小于 0:相等 正数:大于 按照ASCII码比较,只要发现不相等的内容算出差值直接返回,不会继续向下查找。 9.字符串查找 表的1 6 7 8 contains indexOf:int startsWith endsWith 10.字符串替换 public Str...
如果属性值以两个 ASCII 字符 0x 或者 ASCII 字符 # 开始,并且后面没有减号,则将它的剩余部分解析为十六进制整数,就好像以 16 为基数调用 valueOf(java.lang.String, int) 方法一样。 如果属性值以 ASCII 字符 0 开始,后面还有其他字符,则将它解析为八进制整数,就好像以 8 为基数调用 valueOf(java.lang.St...
