Java program to perform Bubble Sort on Strings
INSTAGRAM : / javac_programming
To perform bubble sort on Strings we need to compare adjacent Strings and if they are not in the order then we need to swap those strings, this process needs to be done until we reach at the end. This way all the strings will be sorted in an ascending order, this process of sorting is known as bubble sorting.
Bubble Sort on Strings example
In the following example we have stored the strings in a String array and we are using nested for loops to compare adjacent strings in the array, if they are not in order we are swapping them using a temporary string variable temp.
Here we are using compareTo() method to compare the adjacent Strings.
public class JavaExample {
public static void main(String []args) {
String str[] = { "Ajeet", "Steve", "Rick", "Becky", "Mohan"};
String temp;
System.out.println("Strings in sorted order:");
for (int j = 0; j _ str.length; j++) {
for (int i = j + 1; i _ str.length; i++) {
// comparing adjacent strings
if (str[i].compareTo(str[j]) _ 0) {
temp = str[j];
str[j] = str[i];
str[i] = temp;
}
}
System.out.println(str[j]);
}
}
}
