What is the difference between break point and watch point?
Unlike breakpoints, which are line-specific, watchpoints are event-specific and take effect whenever a specified condition is true, regardless of when or where it occurred. An event breakpoint is similar to breakpoint that’s set on a specific event rather than a specific line of source code.
What is watchpoint Java?
Watchpoint. A watchpoint is a breakpoint set on a field. The debugger will stop whenever that field is read or changed. You can set a watchpoint by double-clicking on the left margin, next to the field declaration.
What is line breakpoint in eclipse?
A breakpoint is a signal that tells the debugger to temporarily suspend execution of your program at a certain point in the code. To define a breakpoint in your source code, right-click in the left margin in the Java editor and select Toggle Breakpoint. Alternatively, you can double-click on this position.
How do I apply a conditional breakpoint in eclipse?
First, set a breakpoint at a given location. Then, use the context menu on the breakpoint in the left editor margin or in the Breakpoints view in the Debug perspective, and select the breakpoint’s properties. In the dialog box, check Enable Condition, and enter an arbitrary Java condition, such as list.
What is a watchpoint?
Similarly, a watchpoint is a type of breakpoint that indicates an area of memory associated with a data item that you want to watch, pausing your application when that memory is updated. These types of breakpoint are set on a data item, as opposed to a particular line of code.
How do watchpoints work?
Watchpoints. A watchpoint is similar to a breakpoint, but it is the address of a data access that is monitored rather than an instruction being executed. You specify a global variable or a memory address to monitor. Watchpoints are sometimes known as data breakpoints, emphasizing that they are data dependent.
What is a watchpoint in debugging?
A watchpoint is a conditional breakpoint that is only defined in the ABAP Debugger during a running debug session. It is one of the runtime utilities provided to stop and debug ABAP programs. When debugging ABAP code, you can use watchpoints to track the value of individual ABAP variables.
What is a watchpoint in code?
What is line break point?
A line breakpoint causes the execution of a thread to suspend at the location where the breakpoint is set. Line breakpoints are set on an executable line of a program.
What is a breakpoint in debugging?
Breakpoints are one of the most important debugging techniques in your developer’s toolbox. You set breakpoints wherever you want to pause debugger execution. For example, you may want to see the state of code variables or look at the call stack at a certain breakpoint.
What is a conditional breakpoint?
Conditional breakpoints allow you to break inside a code block when a defined expression evaluates to true. Conditional breakpoints highlight as orange instead of blue. Add a conditional breakpoint by right clicking a line number, selecting Add Conditional Breakpoint , and entering an expression.

Why are watchpoints used?
Using watchpoints, you can rapidly detect unexpected alterations to Natural variables by objects that contain errors. By default, watchpoints are used to instruct the debugger to interrupt the execution of Natural objects when the content of a variable changes.
What is a breakpoint code?
In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause.

- Enter a valid condition in the corresponding entry field. See also: Conditions for Watchpoints. Editing a watchpoint condition.
What is true watch point?
In SAP, a watchpoint is a conditional breakpoint that is only defined in the ABAP Debugger. It is one of the runtime utility components provided to debug SAP application programs and serves as an indicator to the ABAP runtime processor to interrupt further program processing from the specified point or relation.
How do I turn off watch point?
Deleting Watchpoints
Choose Goto ® Control debugging ® Watchpoints or the Watchpoints pushbutton to display the watchpoint list. Choose the trashcan icon in the line containing the watchpoint you want to delete.
Why do we use breakpoints?
Breakpoints are most commonly used to interrupt a running program immediately before the execution of a programmer-specified instruction. This is often referred to as an instruction breakpoint.
How does a breakpoint work?
Software Breakpoint
They work by patching the code you are trying to execute with an instruction that triggers a debug event in some fashion. This is accomplished by injecting a breakpoint instruction or when that is not supported by inserting an instruction that causes a fault that halts the core.
What is a breakpoint error?

Use conditional breakpoints to conditionally stop program execution. Breakpoints normally stop the execution every time a certain line or function is reached. However, using the condition keyword, a breakpoint will only be activated if a certain condition is true.
