To replace one string with another string using Java Regular Expressions, we need to use the replaceAll() method. The replaceAll() method returns a String replacing all the character sequence matching the regular expression and String after replacement.
The replace() method returns a copy of the string where the old substring is replaced with the new substring. The original string is unchanged. If the old substring is not found, it returns the copy of the original string.
To replace a character in a String, without using the replace() method, try the below logic. Let's say the following is our string. int pos = 7; char rep = 'p'; String res = str. substring(0, pos) + rep + str.
Java String replaceAll() The Java String class replaceAll() method returns a string replacing all the sequence of characters matching regex and replacement string.
The replace method is what you're looking for.
For example:
String replacedString = someString.replace("HelloBrother", "Brother"); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
