Java--return

Two functions of 1.return: End the run of the method, return the value.
Example
public static int {


if (a==3) {


return 0;
}


System.out.print ("heh"); The following two-segment code is not executed when a==3. The operation of the method is terminated directly.
return 5;

}
Only value is passed in 2.Java.
3. Principles of Design methodology: The intent of a method is a function block, which is a collection of statement blocks that implement a function. When we design a method, it is best to maintain the atomicity of the method, which is a method that only accomplishes one function, which facilitates our later expansion.
