Long story short personal project of mine, I am trying to re-do the implementation of something. However, there are many uses of this method and it would take me too much time to do it manually.

Using the change method signature window, I can easily change an abstract method of

public abstract void run(int a, int b);

to

public abstract int run(int a, int b);

That part is easy enough and I know how to do it.

However, I'd also like to be add:

Before:

@Override    
public void run(int a, int b) {
   /* irrelevant code here */
}

After:

@Override    
public int run(int a, int b) {
    /* irrelevant code here */
  return -1;
}

Is this possible with any of the tools Intellij has to offer?

CodePudding user response：

Depending on the complexity of your irrelevant code you might be able to get away with using a regex for this.

Something along the lines of:
Find: (\@Override\npublic void run\(int a\, int b\) \{)(.|\n*?)(^})
Replace: $1$2return -1;\n$3

Find explanation:

• (\@Override\npublic void run\(int a\, int b\) \{) first part of the method
• (.|\n*?) Find any number of any character (including new lines \n); non greedy (?)
• (^}) Last/Closing line of the method.
  • Shown here as a line that starts with a closing bracket, but should be changed to match whatever matches the end of your method. Likely four spaces (^\s\s\s\s}) or a tab (^\t})

Replace explanation:

• $1 first found section
• $2 second found section
• return -1;\n new code to add
• $3 third found section
