注意“/”和“-”,"&"不是转义字符。

String str="aaaa/aaaa/aaaa";
            String[] strings=str.split("/");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa-aaaa-aaaa";
            String[] strings=str.split("-");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa&aaaa&aaaa";
            String[] strings=str.split("&");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa|aaaa|aaaa";
            String[] strings=str.split("\\|");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa\\aaaa\\aaaa";
            String[] strings=str.split("\\\\");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa$aaaa$aaaa";
            String[] strings=str.split("\\$");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa*aaaa*aaaa";
            String[] strings=str.split("\\*");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa+aaaa+aaaa";
            String[] strings=str.split("\\+");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa.aaaa.aaaa";
            String[] strings=str.split("\\.");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa?aaaa?aaaa";
            String[] strings=str.split("\\?");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa^aaaa^aaaa";
            String[] strings=str.split("\\^");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

String str="aaaa(aaaa(aaaa";
            String[] strings=str.split("\\(");
            for (int i = 0; i < strings.length; i++) {
                System.out.println(strings[i]);
            }

所有的括号都是转义字符
