• It is a reference type.
• Syntax:

  • String str = "Hello".
• Strings are immutable in Java.

OPERATIONS

• ‘+’ : Concatenates two strings.
• endsWith(): Checks if a string ends with a specific substring.
• length(): Retrieves the length of a string.
• indexOf(): Retrieves the index of a character in a string.
• replace(): Replaces a character in a string with another.
• toLowerCase(): Converts the string to lowercase.
• toUpperCase(): Converts the string to uppercase.
• trim(): Removes leading and trailing whitespace from the string.

When we use operations to modify a string, they create new strings based on our operation and assign the new string to our original string.

Escape Sequences

• In a String, we cannot type a backslash (\) directly. If we want to use it, we have to type another backslash (\\).
• \n represents a new line, and \t represents a tab
