Line breakpoints are set on an executable line of a program.
Also, the new breakpoint appears in the Breakpoints View list.
While the breakpoint is enabled, execution suspends before that line of code is executed. The debugger displays the execution stack frames. The line where the breakpoint was set is highlighted in the editor in the Debug Perspective.
