1.6.1 For Loops

Examples of for loops

/**

* An example of a method containing a for loop

public void sampleForLoop()

{

String str;

str ="";

for(int x = 0; x<5; x++){

str = str +"*";

}

System.out.println(str);

}

Note: When + is used to add two or more Strings together, the strings are joined together. Joining of two or more strings is called concatenation

public void sumOneToTen()

{

int sum;

sum =0;

for(int x = 1; x <= 10; x++){

sum = sum + x;

}

System.out.println(sum);

}

public void sumFirstTenEvenNumbers()

{

int sum;

sum =0;

for(int x = 1; x <= 10; x++){

sum = sum + x*2;

}

System.out.println(sum);

}

public void sumStartToStop()

{

int sum, start, stop;

sum =0;

start =9;

stop = 15;

for(int x = start; x <= stop; x++){

sum = sum + x;

}

System.out.println(sum);

}
