Question
Which of the following methods can be used to decompose strings in Java?
string.splice()string.substring()string.trim()string.cut()
Clear my choice
Solution
In Java, the correct method to decompose strings from the options provided is string.substring().
Explanation of Each Option:
-
string.splice(): This method does not exist in Java. It might be confused with array manipulation in JavaScript.
-
string.substring(): This method is used to extract a portion of a string based on specified indices and is definitely a valid method for string decomposition in Java. For example,
String sub = str.substring(startIndex, endIndex);extracts the substring from the given start index to end index. -
string.trim(): This method is used to remove whitespace from both ends of the string but does not decompose or split the string into parts.
-
string.cut(): This method does not exist in Java as well.
Final Answer:
The correct method for string decomposition in Java from the given options is string.substring().
