Sometimes, suspending And Stop Threads

Sometimes, suspending And Stop Threads   Sometimes, suspending execution of a thread is useful. For example, a separate thread can be used to display the time of day. If the user doesn’t want a clock, then its thread can be suspended. Whatever the case, suspending a thread is a simple matter . .once suspended, restarting the…

Suspending, Resuming, and Stopping Threads Using Java 1.1 and Earlier

Suspending, Resuming, and Stopping Threads Using Java 1.1 and Earlier Prior to Java 2, a program used suspend( ) and resume( ), which are methods defined by – Thread, to pause and restart the execution of a thread. TIlKY have the form shown below: final void suspend( ) final void resume(  ) The following program demonstrates these…

Suspending, Resuming, and Stopping Threads Using Java 2

Suspending, Resuming, and Stopping Threads Using Java 2 While the suspend ( ), resume( ), and stop( ) methods defined by Thread seem to be a perfectly reasonable and convenient approach to managing the execution of threads, they must not be used (or new Java programs. Here’s why. ‘The suspend () method of the Thread class is deprecated…

Using Multi threading

Using Multi threading If you are like most programmers, having multithreaded support built into the language will be new to you. The key to”utilizing this ‘support effectively is to think . concurrently rather than serially. For example; when you have two subsystems within a program that can execute concurrently, make them individual threads. With the . careful use of…

Using the Comma

Using the Comma There will be times when you will want to include more than one statement in the initialization and iteration portions of the for loop. For example, consider the loop in the following program: As you can see, the loop is controlled by the interaction of two variables. Since the loop  is go vented…

Declaring Lop Control Variables Inside the for Loop

Declaring Lop Control Variables Inside the for Loop Offend tile variable that controls for loop Is only needed for the purposes of the loll and is not used elsewhere. When this is the case, it is possible to declare the capable  inside the initialization portion of the for. For example, here is the preceding program receded so…

do-while

do-while As you just saw, if the.conditional expression con(while Joop is initially false  then the body of the loop will not be executed at However, sometimes it is desirable to  the body of a while loop’ at least on get even if the conditional expression ‘ls . false to begin with. In other words, there arc  you…

Iteration Statements

Iteration Statements Java’s iteration statements are for, while, and do-while. These statements create what we commonly call/oops. As you probably know, a loop repeatedly executes the same set of instructions until a termination condition is met. As you will see, Java has a loop to fit any programming need. while The while loop is Java’s most fundamental looping…

The Complete Reference

The Complete Reference  Multithreaded Programming  most other computer languages, Java provides built-in support for multithreaded programming. A multithreaded program contains two or more ‘parts that can run concurrently. Each part of such a program is called a thread, and each thread defines a separate path of execution. Thus, multithreading is a  specialized form of multitasking. ‘ , You are almost certainly…

Nested switch Statements

Nested switch Statements You can use a switch as part of the statement sequence of an outer switch. This is called a nested switch. Since a switch statement defines its own block, no conflicts arise – between the case constants in.the inner switch and those in the outer switch. For example, the following fragment js perfectly valid: Here…
