String str="shiva"; #2 How to create String object? -- using new operator String str=new String("shiva"); -- directly assigning String str="shiva"; put sequence of character inside a double quotes. #3 What is hashcode? -- hashcode is unique number for each object created in heap. -- hashcode is used to identify object. #4 Concatenation operator -- + operator used to concatenate the String String firstName="shiva"; String lastName="srivastava"; String fullName=firstName+lastName; System.out.println(fullName); //shivasrivastava #5 some method used in String a) int length() --to find the length of String b) char charAt(int index) --to find character at particular index System.out.println(str.charAt(0)); System.out.println(str.length()); Note: In array length is property while in String length() is method.
