如何检查字符串是否包含包含空格的子字符串？

问题描述：

假设我在java中有这样的字符串：

Say I have a string like this in java:

这是{my string：} ok

"this is {my string: } ok"

请注意，各个字符之间可以有任意数量的空格。如何检查上面的字符串以查看它是否只包含子字符串：

Note, there can be any number of white spaces in between the various characters. How do I check the above string to see if it contains just the substring:

{my string：}

"{my string: }"

非常感谢！

答

如果您想查看String是否包含另一个特定的字符序列，那么您可以做这样的事情：

If you are looking to see if a String contains another specific sequence of characters then you could do something like this :

String stringToTest = "blah blah blah";

if(stringToTest.contains("blah")){
    return true;
}

您也可以使用匹配。有关匹配字符串的合适解释，我建议您查看正则表达式的Java Oracle教程：

You could also use matches. For a decent explanation on matching Strings I would advise you check out the Java Oracle tutorials for Regular Expressions at :
