Java反编译代码分析（一）

浅析如何读懂这种反编译过来的文件，不喜勿喷。

Node node;        Node node1 = _$3.getChildNodes().item(0);        node1;        node1;        JVM INSTR swap ;        node;        getChildNodes();        0;        item();        getChildNodes();        0;        item();        getNodeValue();        String s;        s;

原始语句：

Node node;Node node1 = currDocument.getChildNodes().item(0);node = node1;String s = node.getChildNodes().item(0).getChildNodes().item(0).getNodeValue();

//赋值语句// JVM INSTR swap ;

JVM INSTR new #244 <Class CrossTable>;        JVM INSTR dup ;        JVM INSTR swap ;        CrossTable();        CrossTable crosstable;        crosstable;

CrossTable crosstable = new CrossTable();

JVM INSTR new #262 <Class StringBuffer>;        JVM INSTR dup ;        JVM INSTR swap ;        String.valueOf(s2);        StringBuffer();        s.substring(j, i);        append();        s6;        append();        toString();        s2;

s2 = (new StringBuffer(String.valueOf(s2))).append(s.substring(j, i)).append(s6).toString();//s2 += s.substring(j, i) + s6;

int k = 0;goto _L4_L8: ... k++;_L4:        if(k < as.length) goto _L8; else goto _L7

for(int k=0;k < as.length;k++) {     ... }

String s1 = "";          goto _L1_L3:        JVM INSTR new #262 <Class StringBuffer>;        JVM INSTR dup ;        JVM INSTR swap ;        String.valueOf(s1);        StringBuffer();        _$2(resultset, s, l);        append();        toString();        s1;_L1:        if(resultset.next()) goto _L3; else goto _L2

String s1 = ""; while(resultset.next()) {  s1 = s1 + resultSetToString(resultset, s, l); }
