There is any way to set admin user from java and through this i can access node and all child node .in my case if i have login with any user and i pass nodeId to fetch all child node of node. so i am thinking i will set admin user in java code and using admin i can fetch all child node for any us

In your custom logic you can use - AuthenticationUtil.runAsUser(..)

Instead of setting user as admin, better to use system user which doesn't affect security context.

Here is a sample example for what you want to get:

final List<ChildAssociationRef> childNodes = nodeService.getChildAssocs(parentNodeRef);
for (final ChildAssociationRef eachChildAssocRef : childNodes) {
    final NodeRef childRef = eachChildAssocRef.getChildRef();
    //TODO:: DO SOMETHING...

}

/**
 * Gets the child nodes.
 *
 * @param parentNodeRef the parent node ref
 * @return the child nodes
*/
private List<ChildAssociationRef> getChildNodes(final NodeRef parentNodeRef) {
		final List<ChildAssociationRef> childAssocs = AuthenticationUtil.runAs(
				new AuthenticationUtil.RunAsWork<List<ChildAssociationRef>>() {
					public List<ChildAssociationRef> doWork() throws Exception {
						return nodeService.getChildAssocs(parentNodeRef);
					}
				}, AuthenticationUtil.getSystemUserName());

		return childAssocs;
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Or simply run your whole operation by setting the authentication as system user based on your use case if you want to do many such operations like getting child-nodes...

Here is a sample example:

AuthenticationUtil.setRunAsUserSystem();
final List<ChildAssociationRef> childNodes = nodeService.getChildAssocs(parentNodeRef);
 for (final ChildAssociationRef eachChildAssocRef : childNodes) {
   final NodeRef childRef = eachChildAssocRef.getChildRef();
   //TODO:: DO SOMETHING...
   final Map<QName, Serializable> properties = nodeService.getProperties(childRef);
   //TODO:: DO SOMETHING...

 }‍‍‍‍‍‍‍‍‍
 // More operations which bypasses current user permissions and run as system user
 //TODO:: DO SOMETHING...‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
