calling javascript

How do you call stylesheets like javascript.js files?
<script language=”JavaScript1.2″ src=”java/javascript1.js”>
</script>

Can this be done and would this be considered a stylesheet?

<style>
<!–
.itemBorder { border: 1px solid black }
.itemText { text-decoration: none; color: #FFFFFF; font: 14px Arial, Helvetica }
.itemText2 { text-decoration: none; color: #000066; font: 16px Arial, Helvetica }
.crazyBorder { border: 2px outset #663399 }
.crazyText { text-decoration: none; color: #FFCC99; font: Bold 12px Arial, Helvetica }
–>
</style><style>
.hovered {
text-align: center;
background-color:#0000A0;
border-style:solid;
border-width:1px;
border-color:#FFFFFF #808080 #808080 #FFFFFF;
width: 80px;
height:15px;
color: #FFFFFF;
font-family: arial, sans serif;
font-size: 13px;
cursor: default;
}
.normal{
text-align: center;
background-color:#C0C0C0;
border-style:solid;
border-width:1px;
width: 80px;
height:15px;
border-color:#C0C0C0;
color: #000000;
font-family: arial, sans serif;
font-size: 13px;

}
</style>
