Arrays.toString () method returns the string of the input array. Hence these variables are known as instance variables, _______________________________________________________________. Logical AND operator: This operator tends to return a true value if the satisfactory conditions are true. Advance level (7 or above) years experienced. The logic of this program is a little tricky because there are two processes, i.e., finding the duplicate characters and occurrence of that character. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Method 2: This is another method in which you are declaring your string variable str and then using Scanner class to declare an object with a predefined standard input object.
