如何使用CodeModel初始化二维数组

import com.sun.codemodel.*;

public class CodeModelExample {
    public static void main(String[] args) throws Exception {
        JCodeModel codeModel = new JCodeModel();
        JDefinedClass definedClass = codeModel._class("MyClass");
        
        JMethod method = definedClass.method(JMod.PUBLIC | JMod.STATIC, void.class, "initializeArray");
        JBlock body = method.body();
        
        JVar arrayVar = body.decl(codeModel.INT.array().array(), "myArray");
        JArray arrayInit = JExpr.newArray(codeModel.INT.array());
        arrayInit.add(JExpr.newArray(codeModel.INT).add(JExpr.lit(1)).add(JExpr.lit(2)));
        arrayInit.add(JExpr.newArray(codeModel.INT).add(JExpr.lit(3)).add(JExpr.lit(4)));
        
        body.assign(arrayVar, arrayInit);
        
        codeModel.build(new File("src"));
    }
}
