Mac reports various versions of Java in the command terminal and system settings

Question

On my Mac, the Java version specified in the command terminal is 1.7.0_40. Java Control Panel (System Preferences) indicates 1.7.0_51.

Why are they different?

Additional Information:

From the command terminal /usr/libexec/java_home -V replies:

 Matching Java Virtual Machines (3): 1.7.0_40, x86_64: "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home 1.6.0_65-b14-462, x86_64: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 1.6.0_65-b14-462, i386: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 

JAVA_HOME set to:

 /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home 

From the command terminal, java -version responds:

Answer 1

When you run the java command line, it launches the configuration specified in the path to your system.

The other in the system settings must be selected from another location on your system.
