How could I remove connectors: "and", "do", "of", "of", "of", "of", "di", "du". One sentence without changing the whole name.
Example name: Daniela de Andrade. I want to remove only "from", without removing the "DA" from andra "FROM" I am using relaceAll function in java.
String retiraConector = "^\s e $\s";
nome = nome.replaceAll(retiraConector, " ");
You can use the following pattern:
String padrao = "(\w)(\s+)(e|do|da|do|das|de|di|du)(\s+)(\w)";
This pattern has been divided into five groups, these follow the order:
+ + one or more spaces + any letter or numberNote: groups are formed through parentheses.
To make the replacement use:
public static void main(String[] args) {
String padrao = "(\w)(\s+)(e|do|da|do|das|de|di|du)(\s+)(\w)";
String nome = "Daniela de Andrade";
System.out.println(nome.replaceAll(padrao, "$1 $5"));
}
The result is as follows:
Daniela Andrade
When you use replaceAll , the default is found in Daniel[a de A]ndrade , and is replaced by groups 1 and 5, which are separated by white space, these groups are represented by a > from Daniel to and A , A ndrade.
Review
To ignore uppercase and lowercase letters, you can use (?i) in your expression, for example:
String padrao = "(?i)(\w)(\s+)(e|do|da|do|das|de|di|du)(\s+)(\w)";
The way to do the substitution is the same one as above.
Following the response from @Mateus Alexandre:
You can use the following pattern as well:
String padrao = "\s(e|d(a|e|i|o|u)s?)\s";
This pattern has been divided into two groups, these follow the order:
space space space connector
just changing:
System.out.println(nome.replaceAll(padrao, "$1 $5"));
for
System.out.println(nome.replaceAll(padrao, " "));
