The replace method is what you're looking for.

替换方法就是你要找的。

For example:

例如:

String replacedString = someString.replace("HelloBrother", "Brother");

#2

Try this: http://download.oracle.com/javase/7/docs/api/java/lang/String.html#replace%28char,%20char%29

试试这个:http://download.oracle.com/javase/7/docs/api/java/lang/String.html取代% 28 char,% 20字符% 29

String a = "HelloBrother How are you!";
String r = a.replace("HelloBrother","Brother");

System.out.println(r);

This would print out "Brother How are you!"

这会打印出“兄弟你好!”

有可能不使用额外的变量

String s = "HelloSuresh";
s = s.replace("Hello","");
System.out.println(s);
