7 it is the bitwise xor operator in java which results 1 for different value of bit (ie 1 ^ 0 = 1) and 0 for same value of bit (ie 0 ^ 0 = 0) when a number is written in binary form

The binary representation of 5 is 0101 The binary representation of 4 is 0100. In the following link it gives the following explanation, which is quiet good to understand it A ternary operator is some operation operating on 3 inputs In perl/php it works as: In java persistence api you use them to map a java class with database tables

For example @table () used to map the particular java class to the date base table @entity represents that the class is an entity class Similarly you can use many annotations to map individual columns, generate ids, generate version, relationships etc. In java, == and the equals method are used for different purposes when comparing objects Here's a brief explanation of the difference between them along with examples: I always thought that &&amp

Operator in java is used for verifying whether both its boolean operands are true, and the &amp

While hunting through some code i came across the arrow operator, what exactly does it do I thought java did not have an arrow operator Java has 5 different boolean compare operators &, &&, |, ||, ^ & and && are and operators, | and || or operators, ^ is xor the single ones will check every parameter, regardless of the values, before checking the values of the parameters The double ones will first check the left parameter and its value and if true (||) or false (&&) leave the second one untouched Java_home if you installed the jdk (java development kit) or jre_home if you installed the jre (java runtime environment)

In the variable value field, enter your jdk or jre installation path Open command prompt as administrator Set the value of the environment variable to your jdk (or jre) installation path as follows: This value must a multiple of 1024 greater than 2mb Append the letter k or k to indicate kilobytes, or m or m to indicate megabytes The default value is 64mb

The upper limit for this value will be approximately 4000m on solaris 7 and solaris.

Start your remote java application with debugging options as said in above post Configure eclipse for remote debugging by specifying host and port Start remote debugging in eclipse and wait for connection to succeed If you want to debug from start of application use suspend=y , this will keep remote application suspended until you connect from eclipse
