例1：

class Outer {public void md1(final int a) {final int b = 1;class LocalA {int c = a;}class LocalB extends LocalA {LocalB() {super();}}}}

解语法糖后的形式如下：

class Outer { public void md1(final int a) { final int b = 1; }}class Outer$1LocalA {/* synthetic */ final Outer this$0;/* synthetic */ final int val$a;Outer$1LocalA(/* synthetic */ final Outer this$0, /* synthetic */ final int val$a) {this.this$0 = this$0;this.val$a = val$a;super();}int c = val$a;}class Outer$1LocalB extends Outer$1LocalA { /*synthetic*/ final Outer this$0; /*synthetic*/ final int val$a; Outer$1LocalB(/*synthetic*/ final Outer this$0, /*synthetic*/ final int val$a) { this.this$0 = this$0; this.val$a = val$a; super(this$0, val$a); }}

例2：

class Outer {public void md1(final int a,final int b) {class LocalA {int c = b;class LocalB {int d = a;}}}} 

解语法糖后如下：

class Outer {public void md1(final int a, final int b) {}}class Outer$1LocalA {/* synthetic */ final Outer this$0;/* synthetic */ final int val$a;/* synthetic */ final int val$b;Outer$1LocalA(/* synthetic */ final Outer this$0, /* synthetic */ final int val$b, /* synthetic */ final int val$a) {this.this$0 = this$0;this.val$b = val$b;this.val$a = val$a;super();}int c = val$b;}class Outer$1LocalA$LocalB {/* synthetic */ final Outer$1LocalA this$1;Outer$1LocalA$LocalB(/* synthetic */ final Outer$1LocalA this$1) {this.this$1 = this$1;super();}int d = this$1.val$a;}

例3：

class Outer {public void md1(final int a) {class LocalA {int x1 = a;}class LocalB { Object x2 = new LocalA();}}}

解语法糖后如下：

class Outer { public void md1(final int a) { }}class Outer$1LocalA { /*synthetic*/ final Outer this$0; /*synthetic*/ final int val$a; Outer$1LocalA(/*synthetic*/ final Outer this$0, /*synthetic*/ final int val$a) { this.this$0 = this$0; this.val$a = val$a; super(); } int x1 = val$a;}class Outer$1LocalB { /*synthetic*/ final Outer this$0; /*synthetic*/ final int val$a; Outer$1LocalB(/*synthetic*/ final Outer this$0, /*synthetic*/ final int val$a) { this.this$0 = this$0; this.val$a = val$a; super(); } Object x2 = new Outer$1LocalA(this$0, val$a);}

例4：

class Test { public void md1(final int a) {class Outer {class Inner {int c = a;}} class LocalC extends Outer.Inner{ LocalC(Outer a){ a.super(); } } }}

解语法糖如下：

class Test$1Outer$Inner { /*synthetic*/ final Test$1Outer this$1; Test$1Outer$Inner(/*synthetic*/ final Test$1Outer this$1) { this.this$1 = this$1; super(); } int c = this$1.val$a;},class Test$1Outer { /*synthetic*/ final Test this$0; /*synthetic*/ final int val$a; Test$1Outer(/*synthetic*/ final Test this$0, /*synthetic*/ final int val$a) { this.this$0 = this$0; this.val$a = val$a; super(); }},class Test$1LocalC extends Test$1Outer$Inner { /*synthetic*/ final Test this$0; Test$1LocalC(/*synthetic*/ final Test this$0, Test$1Outer a) { this.this$0 = this$0; super(a<*nullchk*>); }},class Test { public void md1(final int a) { }}

例5：

class Outer {public void md(final int a) {class AOuter {class BOuter {// final Outer this$0 合成的变量class COuter {// final Outer$AOuter this$1 合成的变量int b = a;}}}}}

解语法糖后如下：

class Outer { public void md(final int a) { }}class Outer$1AOuter { /*synthetic*/ final Outer this$0; /*synthetic*/ final int val$a; Outer$1AOuter(/*synthetic*/ final Outer this$0, /*synthetic*/ final int val$a) { this.this$0 = this$0; this.val$a = val$a; super(); }}class Outer$1AOuter$BOuter { /*synthetic*/ final Outer$1AOuter this$1; Outer$1AOuter$BOuter(/*synthetic*/ final Outer$1AOuter this$1) { this.this$1 = this$1; super(); }}class Outer$1AOuter$BOuter$COuter { /*synthetic*/ final Outer$1AOuter$BOuter this$2; Outer$1AOuter$BOuter$COuter(/*synthetic*/ final Outer$1AOuter$BOuter this$2) { this.this$2 = this$2; super(); } int b = this$2.this$1.val$a;}
