Java - replace all occurrences of string
0 points
In this article, we would like to show you how to replace all occurrences of string in Java.
Quick solution:
xxxxxxxxxx1
String text = "ABC ABC ABC";2
String replacement = "X";3
String result = text.replaceAll("C", replacement);4
5
System.out.println(result); // ABX ABX ABX
In this example, we use replaceAll() method to replace all occurrences of the "C" in the text string to "X".
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABC ABC ABC";5
String replacement = "X";6
String result = text.replaceAll("C", replacement);7
8
System.out.println("Original text: " + text); // ABC ABC ABC9
System.out.println("Modified text: " + result); // ABX ABX ABX10
}11
}Output:
xxxxxxxxxx1
Original text: ABC ABC ABC2
Modified text: ABX ABX ABXIn this example, we use replace() method to replace all occurrences of the "C" in the text string to "X".
xxxxxxxxxx1
public class Example {2
3
public static void main(String[] args) {4
String text = "ABC ABC ABC";5
String replacement = "X";6
String result = text.replace("C", replacement);7
8
System.out.println("Original text: " + text); // ABC ABC ABC9
System.out.println("Modified text: " + result); // ABX ABX ABX10
}11
}Output:
xxxxxxxxxx1
Original text: ABC ABC ABC2
Modified text: ABX ABX ABXNote:
The difference between
replace()andreplaceAll()is insignificant. ThereplaceAll()method takes regex as the first argument, whilereplace()takes char or CharSequence.
