Do I want to check if the String that was generated by some method is equal to something that I want to verify with? How do I compare two Strings? The result will have the value 0 if the argument string is equal to this string; a value less than 0 if this string is lexicographically less than the string argument; and a value greater than 0 if this string is lexicographically greater than the string argument.
I partially know what the string should have contained, how do I confirm if the String contains a sequence of characters I specify? Returns true if and only if this string contains the specified sequence of char values. How do I confirm if a String ends with a particular suffix? Again you answered it. Returns true if the character sequence represented by the argument is a suffix of the character sequence represented by this object. Java String Replace, replaceAll and replaceFirst methods.
You can specify the part of the String you want to replace and the replacement String in the arguments. I'm just saying that if String. Add a comment.

Since s would have been an array itself. This can be achieved by using java.
Kartik Kartik 1. Can you add some explanation to this code only answer? Yes, Java has a class StringReader for reading the character stream from string. Its read method returns -1 if no character is read so I have used that to check if it is the end of string or not.
I have stored the character one by one in a char array and after whole string characters are read, I have returned that array.

Let's understand how to search and sort elements in String Array. In the above example, we have initialized a boolean variable x to false and an index variable to iterate through the string. Also, we have declared a local variable String variable s to be searched.
Here, the break keyword will exit the loop as soon as the string is found. The sorting in the String array is quite easy. It is performed like in a traditional array.
We use a sort method to sort the Array elements. Sorting is easier than searching. Consider the below example to sort a String Array :. From the above example, we can see the elements from a String Array is sorted using the sort method. We can also convert String Array to other data structures such as List, int Array, ArrayList, and more and vice-versa. JavaTpoint offers too many high quality services.

String concatenations: Suppose we have two strings in separate. We want these two strings to be concatenated in one.
Sub-string inside a string: we have a Contain method in Java to deal with the checking of the string inside a string. We can use this function to check with some sequence of characters in a defined string.
We can also use the substring of Java. Cleaning the string with the unwanted character: For this, we can use the Java trim function. This function can be used to remove the space from the beginning and the end of the given string.
String reverse: String reverse is again the part of string manipulation. This is all about getting the string from the last index to the first index.
This function changes the case of the given string to the lower case. We can use this function at the time of string to handle the ignore case with the compareTo function itself.
