[JAVA] for-statement sum

ex) Find the sum of 1 to 10

class A{

public static void main(String[] args){

int sum=0;

sum=sum+1;

sum=sum+2;

sum=sum+3;

sum=sum+4;

sum=sum+5;

sum=sum+6;

sum=sum+7;

sum=sum+8;

sum=sum+9;

sum=sum+10;

System.out.println(sum); 

}

}

an) 55

class A{

public static void main(String[] args){

int sum=0;

for(int a=1; a<11; a=a+1){

sum=sum+a; 

}

System.out.println(sum); 

}

}

an) 55 

ex) 1+2+3+4+5+6+7+8+9+10=55

class A{ 

public static void main(String[] args){

int sum=0;

int a=1; 

for(; a<10; a=a+1){

sum=sum+a; // 

System.out.print(a+"+");

}

sum=sum+a; 

System.out.print(a);
