In this tutorial, We will learn writing java program to Replace First vowel that occurs in the input string with ‘-‘. For any input string, we have to find vowels which occurs very first in the string and print the character after replacing that vowels with ‘-‘.
Case1: If the user enters the string ‘Python is fun’
The output should be ‘Pyth-n is fun’, as the character ‘o’, is first vowel occurs in the string so it is replaced by ‘-‘.
Case2: If the user enters the string ‘Engineer’
The output should be ‘-ngineer’, as the character ‘E’, is first vowel occurs in the string so it is replaced by ‘-‘.
Java Program to Replace First Occurrence of Vowels with ‘-‘ in a String
As the input from the user is ‘Quescol’, the output obtained is ‘Q-escol’, the for’ loop will iterate with each element of the string and checks for the vowels once it found the first vowel, it replaces the vowel with ‘-‘ and terminates the loop by storing the characters into tempStr variable which is returned as the output.
