Java runs on a variety of platforms, such as Windows, MacOS, and the various versions of UNIX.
Sun Micro systems has renamed the new J2 versions as JavaSE, JavaEE and JavaME respectively. Java is guaranteed to be.
Simple Java programme
public class Ex1000 {
/**
* @param args
*/
public static void main(String[]
args) {
// TODO
Auto-generated method stub
double
salary,allowensses,rate;
salary=50000;
if(salary<30000)
rate=0.1;
else
rate=0.05;
allowensses=salary*rate;
System.out.println("Salary
is"+" "+salary);
System.out.println("Alownessess
is"+" " +allowensses );
}
}
DO & While Java Codes
public class Ex1500 {
/**
* @param args
*/
public static void main(String[]
args) {
// TODO
Auto-generated method stub
int i=1;
do
{
System.out.println(i);
i=i+1;
}
while(i<=5);
{
System.out.print(i);
i=i+1;
}
}
}
For Condition in Java
public class Ex1500 {
/**
* @param args
*/
public static void main(String[]
args) {
// TODO
Auto-generated method stub
for(int
i=1;i<=5;i=i+1)
{
System.out.println("Billionpc");
}
}
}
Java Switch & Case Programme
public class Ex1500 {
/**
* @param args
*/
public static void main(String[]
args) {
// TODO
Auto-generated method stub
int marks=90;
int
indicator=marks/10;
String
grade;
switch(indicator)
{
case 0:
case 1:
case 2:
case 3:
case 4:
grade="Fail";
break;
case 5:
case 6:
grade="Pass";
break;
case 7:
grade="Credit";
break;
default:
grade="Disticshion";
}
System.out.println(grade);
}
}
