The most accurate and most boring way to (105) Java is that it is a new computer programming language developed by Sun Microsystems that creates (106) independent programs that can be distributed and nm remotely.

[单项选择] The way in which people use social space reflects their social relationships and their ethnic identity. Early immigrants to America from Europe brought with them a collective style of living, which they retained until late in the 18th century.
