I-Tự Tạo Một Java Method Và Passing Values Vào Method
Đã Tạo.
1.1- Tự tạo method để
cộng các con số tăng liên tục total +=i.
class rextester{
public static void printTotal(){ // tự tạo method nầy và phải co
static
int total = 0;
for(int i = 1 ;
i<=6; i++){
total +=i ;
System.out.println(total);}
}
public static void main(String[] args){
printTotal();} // call method đã tự tạo
}
SUCCESS.
Output.
Compilation
time: 1.03 sec, absolute running time: 0.14 sec,
cpu time: 0.11
sec, memory peak: 23 Mb, absolute service time: 1.19 sec

1.2- PASSING VALUES TO THE PARAMETERS OF
JAVA METHOD
* Value là integer
class rextester{
public static void passMethod(int x){ // tự tạo method nầy và phải có static
System.out.println("Passed
value is :" + x ); }
public static void main(String[] args)
{
int
x = 5;
passMethod(x); } // call và pass integer vào method đã tạo
}
SUCCESS.
Output.
Compilation
time: 1.04 sec, absolute running time: 0.14 sec,
cpu time:
0.09 sec, memory peak: 22 Mb, absolute service time: 1.19 sec
Passed value is :5
* Value là string
class rextester{
public static void passMethod(String str){
System.out.println("Passed value is :" + str );
}
public static void main(String[] args)
{
String str = "Hello My
Friends";
passMethod(str); } // call và pass string vào method
đã tạo
}
SUCCESS.
Output.
Compilation time: 0.94 sec, absolute running time: 0.24 sec,
cpu time: 0.12 sec, memory peak: 23 Mb, absolute service time: 1.18 sec
Passed value is :Hello My Friends
* Value là name
class rextester{
public static void Person(String name){
// tự tạo method nầy.
System.out.println("Passed Name is
:" + name ); }
public static void main(String []args){
String name=
"Henry";
Person(name);} // call và pass string vào method đã
tạo
}
SUCCESS.
Output.
Compilation
time: 1.03 sec, absolute running time: 0.15 sec,
cpu time: 0.1
sec, memory peak: 23 Mb, absolute service time: 1.18 sec
Passed Name is :Henry
II-Tư tạo nhiều
methods và pass data vào những methods đã tạo.
2.1
class Rextester{
public static void Employee(String name){
System.out.println("Name:"+ name );}
public static void empAge(int x){
System.out.println("Age:" + x );}
public static void
main(String args[]){
String
name = "Xaoke";int x =26;
Employee(name);empAge(x); }
}
SUCCESS.
Output. Compilation time: 0.94 sec, absolute
running time: 0.14 sec,
cpu time: 0.09
sec, memory peak: 23 Mb, absolute service time: 1.09 sec
Name:Xaoke
Age:26
2.2
class Rextester{
public static void Test(String name,int x,String skill){
System.out.println(name
+" "+ x +" "+ skill);}
public static void main(String[] args){
String name=
"Henry"; int x=26; String skill="Programmer";
Test(name,x,skill);}
}
SUCCESS.
output
Compilation time: 0.84 sec, absolute running time: 0.13 sec,
cpu time: 0.06 sec, memory
peak: 18 Mb, absolute service time: 0.98 sec

2.3
class Rextester{
public static void Test1(String
name1,int x1,String skill1){
System.out.println(name1
+" "+ x1 +" "+ skill1);}
public static
void Test2(String name2,int x2,String skill2){
System.out.println(name2
+" "+ x2 +" "+ skill2);}
public
static void main(String[] args){
String name1= "Henry"; int x1=26; String
skill1="Programmer";
String name2= "Pano"; int x2=69; String
skill2="Engineer";
Test1(name1,x1,skill1);Test2(name2,x2,skill2); }
}
SUCCESS.
output
Compilation time: 0.83 sec, absolute running time: 0.13 sec,
cpu time: 0.06 sec, memory
peak: 18 Mb, absolute service time: 0.97 sec
