How do you copy a string from one method into another string in another method in java?

You can have two String variables (note that String variables are object references) refer to the same String object like so:
String str1 = "Hello";
String str2 = str1;
Now the str1 and str2 are references for the same String object containing the word "Hello".
If you actually want a new String object with a copy of the contents of the original String, you use the String constructor that takes a String argument, like so:
String str3 = new String(str1);
Now str1 and str3 refer to SEPARATE String objects that happen to contain the same sequence of characters (the word "Hello").
Since Strings objects in Java are immutable, they can be shared without worrying about the contents used by one variable being upset by the use through another variable as might happen with char[] arrays in C or C++ so the first method is probably sufficient for most cases.

∙ 14y agoYou can do that by returning the string from one method and assigning it to the other.
Ex:
public String getName() {
return "Rocky";
}
public String getFullName() {
return getName() + "Balboa";
}
Here the output from the method getName() is assigned to the method getFullName()

What method that returns string representation of the contents of the variable?
Since the question is in the Java category: in Java, the method is called toString(). This method will automatically be invoked if you implicitly convert an object to String type, for example: "The answer is: " + myObject In this example, the String concatenation (the plus sign) forces the object, myObject, to type String - to do this, the object's toString() method will be called.
How do you use indexOf in java?
indexOf is a method of the String class. Since the indexOf method is overloaded, I will be using the indexOf(String str) version in this example. According to the API Documentation, this method "Returns the index within this string of the first occurrence of the specified substring." So, if you wanted to find the position of the letter 'v' in the String 'Java' and print it out, you would do this: String str = "Java"; int i = str.indexOf("v"); System.out.println(i); If the character you passed in the indexOf method does not exist in the String, indexOf would return a -1 (negative one).
How nesting of methods is done in java?
