If the same element is present more than once, the method returns the index of the first occurrence of the element. Note: Index in Python starts from 0, not 1.
Whether you code in JavaScript, Python, Java, PHP, Ruby, or Go, to access the first element of the array you will need to refer to array[0]. This is often confusing Java â String indexOf() Method - This method returns the index within this string of the first occurrence of the specified character or -1, if the character does not occur. int indexOf(int ch, int fromIndex): It returns the index of first occurrence of character ch in the given string after the specified index “fromIndex”. For example, if the indexOf() method is called like this str.indexOf(‘A’, 20) then it would start looking for the character ‘A’ in string str after the index 20. The java string indexOf() method returns index of given character value or substring. If it is not found, it returns -1. The index counter starts from zero.
Trail: Learning the Java Language Lesson: Object Basics and The index of the first character is 0; the index of the last is length()-1 . For example, the following

After you've found the first index, use the overloaded version of indexOf that receives the start index as a second parameter: public int indexOf(int ch, int fromIndex) Returns the index within this string of the first occurrence of the specified character, starting the search at the specified index. The String class provides two methods that allow you to search a string for a specified character or substring: • indexOf( ) Searches for the first occurrence of a character or substring. • lastIndexOf( ) Searches for the last occurrence of a character or substring. These two methods are overloaded in several different ways. In all cases, the methods return the index at which the character Found g first at position : 11 2. String indexOf(char ch, int strt ) : This method returns the index within this string of the first occurrence of the specified character, starting the search at the specified index or -1, if the character does not occur. In this post, we will see how to find the index of an element in a primitive or object array in Java. The solution should either return the index of first occurrence of the required element, or -1 if the element is not present in the array.
The List interface provides four methods for positional (indexed) access to list elements. Lists (like Java arrays) are zero based. Note that these operations may execute in time proportional to the index value for some implementations (the LinkedList class, for example). Thus, iterating over the elements in a list is typically preferable to Java software for your computer, or the Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on or Java download.
