# How shalt thou compile, with patience and practice 1. Compile thy code `javac -cp .:javaparser-1.0.0.jar:./lib/jgrapht-core-1.5.2.jar:./lib/jgrapht-io-1.5.2.jar:./lib/apfloat-1.10.1.jar:./lib/jheaps-0.14.jar CFGGraph/*.java LCA_JP1_0_0.java` `javac -cp .:javaparser-1.0.0.jar:./lib/* CFGGraph/*.java LCA_JP1_0_0.java` 2. Now move forth to victory `java -cp .:javaparser-1.0.0.jar:./lib/jgrapht-core-1.5.2.jar:./lib/jgrapht-io-1.5.2.jar:./lib/ apfloat-1.10.1.jar:./lib/jheaps-0.14.jar LCA_JP1_0_0 Test.java` `java -cp .:javaparser-1.0.0.jar:./lib/* LCA_JP1_0_0 Test.java` 3. PS: On Windows, replace `:` with `;` and `/` with `\` in paths Node 1 (ENTRY): Created FIRST, so it gets ID = 1 Node 2 (EXIT): Created SECOND, so it gets ID = 2 Then we build the rest of the method body starting from node 3 Why we need them: ENTRY marks where the method starts (before any code executes) EXIT marks where the method ends (after return statements) Helps with analysis - clear start/end points for control flow ```java if (val == 5) { // node 8 val = 6; // node 10 } // node 9: MERGE_IF ``` **Node 9 (MERGE_IF) → edge 14**: - Node 9 is where the FIRST if statement merges (after `val = 6;`) - After the merge, control flow continues to the NEXT statement
