Java Program to Replace the Spaces of a String with a Specific Character
In this article, we will understand how to replace the spaces of a string with a specific character. String is a datatype that contains one or more characters and is enclosed in double quotes(“ ”).
Below is a demonstration of the same −
Suppose our input is −
Input string: Java Program is fun to learn Input character: $
The desired output would be −
The string after replacing spaces with given character is: Java$Program$is$fun$to$learn
Algorithm
Step 1 - START Step 2 - Declare a string namely input_string, a char namely input_character. Step 3 - Define the values. Step 4 - Using the function replace(), replace the white space with the specified character. Step 5 - Display the result Step 6 - Stop
Example 1
Here, we bind all the operations together under the ‘main’ function.
public class Demo {
public static void main(String[] args) {
String input_string = "Java Program is fun to learn";
System.out.println("The string is defined as: " +input_string);
char input_character = '$';
System.out.println("The character is defined as: " +input_character);
input_string = input_string.replace(' ', input_character);
System.out.println("The string after replacing spaces with given character is: ");
System.out.println(input_string);
}
}Output
The string is defined as: Java Program is fun to learn The character is defined as: $ The string after replacing spaces with given character is: Java$Program$is$fun$to$learn
Example 2
Here, we encapsulate the operations into functions exhibiting object-oriented programming.
public class Demo {
static void space_replace(String input_string, char input_character){
input_string = input_string.replace(' ', input_character);
System.out.println("The string after replacing spaces with given character is: ");
System.out.println(input_string);
}
public static void main(String[] args) {
String input_string = "Java Program is fun to learn";
System.out.println("The string is defined as: " +input_string);
char input_character = '$';
System.out.println("The character is defined as: " +input_character);
space_replace(input_string, input_character);
}
}Output
The string is defined as: Java Program is fun to learn The character is defined as: $ The string after replacing spaces with given character is: Java$Program$is$fun$to$learn
