Answer 1

remove ":$PATH" from the path example: export PATH=$JAVA_HOME/bin

After updated class path in .bashrc execute the command "source .bashrc" from terminal or restart the system

Answer 2

Just try this!It worked for me

export PATH=${JAVA_HOME}/bin:${PATH}

export JAVA_HOME=<path to java file>
export JAVA_HOME=/home/janakan/Applications/jdk1.8.0_241
