Attempts to reduce storage used for the character sequence. If the buffer is larger than necessary to hold its current sequence of characters, then it may be resized to become more space efficient. Calling this method may, but is not required to, affect the value returned by a subsequent cal...
Unbounded BigInteger Biased Generator: This generator focuses on producing specific big integer values with higher probability: Integer.MAX_VALUE + 1, Integer.MIN_VALUE -1, Long.MIN_VALUE - 1, Long.MAX_VALUE + 1, and zero. It also produces big integer numbers of 64 bits uniformly distributed...
Converts all of the characters in this String to upper case using the rules of the given Locale. Stringtrim() Returns a string whose value is this string, with all leading and trailing space removed, where space is defined as any character whose codepoint is less than or equal to 'U+00...
Here are some other String methods for finding characters or substrings within a string. The String class provides accessor methods that return the position within the string of a specific character or substring: indexOf() and lastIndexOf(). The indexOf() methods search forward from the beginni...

Reasoning: You should assign the result of trim back to the String variable. Otherwise, it is not going to work, because strings in Java are immutable.Q7. What is the result of this code?class Main { public static void main (String[] args){ System.out.println(print(1)); } static ...
