Eclipse Common debugging shortcut keys __eclipse

Preface

Master IDE Debugging shortcuts convenient for us to quickly locate the program bug location, for problem solving and efficiency has great help

Eclipse shortcut key settings and modifications

about how to set and modify shortcut keys: Select the menu bar of the window->preferences-> General->key, select a shortcut function, set and binding below, the specific method here no longer repeat. For shortcut key settings, it is best to use the default way, the default shortcut keys used for a long time will naturally become a habit, and in the team with the Hu to bring convenience, if they have their own set of shortcuts and habits, it is inevitable to communicate with others when the code obstacles.

the most commonly used shortcut keys ctrl+1

Quick Fix key ctrl+1 is the most commonly used shortcut in Eclipse, a bit like the fast using class in VS, in the development of IDE usage, as long as you see the fork, you can use the Quick fix key, it can help you to supplement the related package references are not imported, you should use Trycatch, etc.

debugging the most commonly used shortcut keys F5, F6, F7, F8 The most frequently used when debugging the program is the number of shortcuts, which: F5: Step into the inside of the method; F6: Next line of code, step by line; F7: Return to the next line of code at the call

F8: Continue running, skip the current interrupt, run to the next breakpoint, if there is no breakpoint after the current interrupt, then run the program will not be interrupted.

F11: Debugging and starting a program

The effect of the accelerator F7 the second rate is as follows, first code:

Package Javalearn;


Class parent2{  
    
    int i=10;//Parent class variable public  
      
    void SetI (int i) {  
        this.i=i;  (2)
    }  
  
class Samename extends parent2{  
    int i=10;//A variable with the same name as the parent class is public  
      
    static void main (String Args[]) {  
    	samename son=new samename ();  
    	System.out.println ("son.i=" +son.i);  
        Son.seti (m);  (1)
        System.out.println ("After SetI (m): son.i=" +son.i);  (3)
          
        Parent2 Parent=son;  
        System.out.println ("Son as parent:son.i=" +parent.i);  
    }  
      

The above code assumes 19 lines to break point, debug the startup program, interrupt here, press F5 into the method Seti inside, when the breakpoint will jump to 9 lines, then press F7, then the code will return to the call, that is (3) of the position, line 20th
