Question

java中subString截取首位截取字符串末尾截取字符

(HOST = 192.168.1.217)

首位是"HOST" 末尾是')'
不好意思我发错了，整体是
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.217)(PORT = 1521))
截取其中的“HOST = 192.168.1.217”

Answer 1

String str="(HOST = 192.168.1.217)";

String end = str.substring(str.length()-1);

end 就是你要的末尾值。

你的目的是不是就是只是为唯档了指稿乱获取端敬野口号？？

Answer 2

String s = "氏胡野嫌(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.217)(PORT = 1521))";
int beginIndex = s.indexOf("歼脊拦H");
int endIndex = s.lastIndexOf("7");
String news = s.substring(beginIndex, endIndex+1);

Answer 3

我枝橡想问一下，你这长长的字符串怎样来的，如果你想得到猛皮旁IP，用获得IP的方法，再拼接上"HOST="
更准确一点
String s="(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.217)(PORT = 1521))"
String str=s.substring(s.indexOf("HOST"),s.indexOf("握竖PORT")-2)

Answer 4

String a =
"正皮(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.217)(PORT = 1521))";

a = a.substring(a.indexOf("HOST"锋清正));
a = a.substring(0, a.indexOf("银悔)"));

Answer 5

String base = "脊判雹樱帆(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.217)(PORT = 1521))";
String[] strs = base.split("("冲纳);
String result = strs[2].subString(0,str[2].length-1);
