[SOLVED] Printing the file content in particular order in bash

Issue

I have two files. I am doing some action on file1 which generates the another file file2

Here is my file1 content:

class parent {
   public void bye() {statement}   
   public void home1() {statement}
   public void Work() {statement}       
   public void apple() {statement}      
   public void fruits() {statement} 
  }

Here is my produced file2 content:

parent
{
        void parent.<init>() (dex_method_idx=8)  {statement}
        void parent.Work() (dex_method_idx=13) {statement}       
        void parent.apple() (dex_method_idx=9) {statement} 
        void parent.bye() (dex_method_idx=10) {statement} 
        void parent.fruits() (dex_method_idx=11) {statement} 
        void parent.home1() (dex_method_idx=12) {statement} 
}

The generated file2 having fixed pattern. The first function code will always be init paragraph. Then it will print the function code which starts from Capital letter (ex. Work). Then print the remaining function code by alphabetical order.

How could I print the function code of file2 according to the order of file1 function code. Expected output:

parent
{
        void parent.<init>() (dex_method_idx=8)  {statement}    
        void parent.bye() (dex_method_idx=10) {statement} 
        void parent.home1() (dex_method_idx=12) {statement}
        void parent.Work() (dex_method_idx=13) {statement}       
        void parent.apple() (dex_method_idx=9) {statement} 
        void parent.fruits() (dex_method_idx=11) {statement}        
}

Please suggest me an approach.

Solution

When I execute above code, it only display content of file1
It is not displaying above output

This may be due to having a pre-POSIX awk that doesn't know character classes ([:alnum:], [:space:]). Here's a version of Ed Morton's script without character classes:

BEGIN { FS="[ .]+" }
NR==FNR {
    if (/^ *} *$/) inDefs=0
    if (inDefs) map[$4] = $0
    if (/^ *{ *$/) inDefs=1
    next
}
FNR==1 {
    print $2 ORS "{"
    print map["<init>()"]
    next
}
{ print $4 in map ? map[$4] : $0 }
