What is default target for javac in JDK 1.4

[Max-well]

To run the Java code, I have a JRE. JRE starts available to the program core libraries , a virtual machine Java ( JVM, for "Java Virtual Machine ") dependent platform extensions for browsers ( Mozilla) , etc. . A JDK ( Java Development Kit , or SDK for Java) Coupled with programming tools such as a compiler and a debugger. Can anybody know the default target for javac in JDK 1.4. Please answer.

If you develop with java 1.5 , you will have code that will run on jvm 1.5 and higher. You can give instructions to the compiler to make . class 1.4 compatible , 1.3 even 1.2 I think . For cons , the big problem is that the API is not the same. Have code that can run on midlet 1.4 but that depends on classes or methods occurred in 1.5 will not help -> will have to choose your classes . In addition, the computer refuse to compile the old version if you used the new jvm options ( such as a code with Generics can never be compiled as a target jvm 1.4).

When installing a runtime environment independent of the JDK , the wizard will consult. Accept the defaults and click Next. So even if you subsequently delete the installation directory of the JDK ( which also contains a JRE) , you can still run Java programs on your computer. You arrive at the final installation screen , which tells you that the installation went smoothly , and offers to register your JDK .

Installs a true JRE 1.4 or better a JDK 1.4 ( eclipse integrate sources to enable the ctrl + click ). In the preferences of eclipse, " Java - > Installed JRES "adds a new " Standard VM " specifying the install directory of your JRE / JDK 1.4. In the ownership of your project , modify the "build- path " by removing the library of Java 5, then add a new JRE taking your JRE 1.4.
