Below programs illustrate the getReturnType() method of Method class : Program 1: Below program prints Return Type for some specific methods of a class provided as input in main method of program. You can use the return statement to return the value within the body of the method. The idea here is to return a String consisting of all values separated by a delimiter. Example. We can call the private method of a class from another class in Java (which are defined using the private access modifier in Java).. We can do this by changing the runtime behavior of the class by using some predefined methods of Java. This approach is not so neat but still vastly used in many legacy projects to transfer data between model and view. Make sure to declare a method’s return type in its method declaration. Accessing values in another class Java applet 1 ; reading value from another class 1 ; polynomial: problem with overloading operator = 5 ; Use JTextField .getText() value in another class 1 ; unable to get final value from another class file. Suggest me how to pass the value. If needed you can return multiple values using array or an object. When you use a method that returns a value, you need to save what it returns in a variable or use the value in some way for example by printing it out. Here are the steps which you will have to follow to call a method in Java. The problem is the value of variable str is not passed to parse() method. 5. 1). A method can return a value or reference type or does not return a value. It is comprised of a set of statements, and the method itself can be invoked through another statement. Using a delimiter. For example, the getXPos() method will return a turtle’s x position. We refer to non-void methods that return an attribute value as getter methods. add_int(int x,int y) - This part of code should be clear that 'add_int' is the name of method and it is taking two parameters of type int. Your help is very much apprecitated. You can return only one value in Java. If a method declare to return a value, then it must use the return statement within the body of method. int add_int(int x,int y) - 'int' before the method name means that this method will return an integer. I want to pass the str value from readXML method to parse method. Within the body of the method, you use the return statement to return the value. More Examples Tip: Use the void keyword to specify that a method should not have a return value: 14 ; flexgrid,rowdata, coldata 3 ; cant return value from a method 2 ; Get value from another class 17 It is displayed as -1. Return Value: The method returns a Class object that represent the formal return type of the method object. i.e. You declare a method's return type in its method declaration. If a method does not return a value, the method must be declared void and it doesn’t need to contain a return statement. Completes all the statements in the method; Reaches a return statement; or Throws an exception (covered later) Whichever occurs first between the last two. Any method declared void doesn't return a value. When i run this program iam not able to get the length of str. The return keyword finished the execution of a method, and can be used to return a value from a method. The method is basically equal to a function in C, which is used for reusing code. we will get some integer value whenever we will call this method. Thanks in advance, regards, Raghu We then need to split the String using the same delimiter before using the values inside the caller method. completes all the statements in the method, reaches a return statement, or; throws an exception (covered later), whichever occurs first. The private constructor means you must call that method the stylistically‑correct way: What you are doing in your method is creating a local variable referring to the same object as the parameter, and returning that reference without doing anything else with it.
