Check multiple words in string java. How to test if a string contains specific words in Java. The syntax for nextLine method is as follows. Boolean startsWith String str index fromIndex.

If it is not found it returns -1. Boolean matchAny ArraysstreamsplitStringsanyMatchx - xequalssomething. The contains method takes only one argument.

Public String nextLine This method throws the following two exceptions. Java String indexOf The java string indexOf method returns index of given character value or substring. The index counter starts from zero.

It is only a way to take multiple string input in Java using the nextLine method of the Scanner class. Return new String0. The indexOf method The indexOf method of the String class accepts a string value and finds the starting index of it in the current String and returns it.

String splitStrings initStringsplit. NoSuchElementException If the string is. String words strsplit.

Used containsKey method of HashMap to check whether the word present or not. The entire string would have to be scanned for each word which is very inefficient. Java nextLine Method The nextLine method moves the scanner down after returning the current line.

Boolean anyMatch false. Java String split by words from sentence As you can see from the output it worked for the test sentence string. Finally iterate over HashMap keyset and check with each keys value if it is greater than 1 then it is a duplicate word.

For example lets say that the value of the String s is Hi there and we are calling starsWith method like this sstartsWith there 3 then this will return true because we have passed value 3 as fromIndex the searching of keyword there begins from the index 3 of the given string s. It returns true if the String begins with str it starts looking from the specified index fromIndex. String strJava is a programming language.

Multiple replace option for a string in java. Use equals instead as for every Object-Type. Using replaceFirst method.

And later on check anyMatch. For String match. String something whatever.

Using Stringreplace method. This can be done using the methods listed below. If HashMap contains word then increment its value by 1 and If a word is not present put that word as key and value as 1.

It reads String input including the space between the words. Every character in the string is checked for a few conditions. In this program we will be discussing various methods for replacing multiple characters in String.

We can extract words from a string in many way but here I am giving some way to extract a word from string.

String initString String1 String2 String3. So one easy solution would be to change that to. You try to pass an array of strings instead.

Then the static method named Length is called. Boolean matchAll ArraysstreamsplitStringsallMatchx - xequalssomething. Using replaceAll method.

This method returns a new string resulting from replacing all occurrences of old characters in the string. Using Stringreplace method. Which must a single CharSequence.

This method returns -1 if it doesnt find the given string in the current one.
